11-1 Distance and Displacement with on same slide.pptx
This document discusses the concepts of distance and displacement in physics. It begins by defining scalars as quantities that have magnitude only, and vectors as quantities that have both magnitude and direction. Distance is defined as a scalar quantity representing how far an object travels, while displacement is a vector quantity representing the direction and length from a starting point to ending point. Examples are used to demonstrate calculating total distance traveled versus displacement between two points, including when the object moves in multiple directions. The key difference between distance and displacement is that displacement accounts for direction of travel.
PowerpointPT-Distance&Displacement .pptx
This is a lesson about distance and displacement. activities are provided. Distance is the measure of “how much ground an object has covered during its motion” while displacement refers to the measure of “how far out of place is an object.” In this article, let us understand the difference between distance and displacement.
What Is Distance?
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
Let’s understand the concept of distance with the help of the following diagram:
Boy cycling his way back home from a reference point A crossing point C to get to point B
Explanation of distance

Distance Formula
How is Displacement defined?
Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object’s position changes. This change in the position of an object is known as Displacement.

motion, distance displacement speed and velocity
Motion depends on the point of reference. Distance is the total path traveled, regardless of direction, while displacement considers the direction and is the net distance between the starting and ending points. Speed is the distance traveled per unit time while velocity is the rate of change of an object's displacement and includes both magnitude and direction. Acceleration is the rate of change of velocity and can be calculated using the formula a=(v-u)/t, where a is acceleration, v is final velocity, u is initial velocity, and t is time. Motion can be analyzed using graphs of displacement-time and velocity-time. The slope and area under the curves provide information about an object's speed, velocity, and acceleration over time.

Class 9 Science Chapter 7: Motion: NCERT Solutions Notes
Introduction to Motion
Motion is defined as the change in position of an object over time.
Any object can be in a state of motion or at rest.
The study of motion involves analysing the various parameters that describe it, such as distance, displacement, speed, velocity, and acceleration.
Distance and Displacement:
Distance refers to the total path length travelled by an object.
Displacement is the shortest distance between the initial and final positions of an object in a specific direction.
Distance is a scalar quantity, while displacement is a vector quantity, as it includes both magnitude and direction.
Speed and Velocity:
Speed is the rate of change of distance with respect to time. It is a scalar quantity and is calculated as distance divided by time.
Velocity is the rate of change of displacement with respect to time. It is a vector quantity and includes both magnitude and direction.
Average speed is calculated by dividing the total distance travelled by the total time taken.
The average velocity is calculated by dividing the total displacement by the total time taken.
Acceleration:
Acceleration is the rate of change of velocity with respect to time.
It can be positive (when an object speeds up), negative (when an object slows down), or zero (when an object moves with constant velocity).
Acceleration is a vector quantity and is calculated as the change in velocity divided by the time taken.
Equations of motion:
Three equations of motion describe the relationship between initial velocity, final velocity, acceleration, displacement, and time.
These equations are derived from the kinematic equations and are used to solve motion-related problems under constant acceleration.
Graphical Representation of Motion:
Motion can be represented graphically using distance-time graphs and velocity-time graphs.
A distance-time graph shows how the distance travelled by an object changes over time.
A velocity-time graph shows how the velocity of an object changes over time.
The slope of a distance-time graph represents the speed of the object, while the slope of a velocity-time graph represents the acceleration.
Uniform and non-uniform motion:
Uniform motion occurs when an object covers equal distances in equal intervals of time.
Non-uniform motion occurs when an object covers unequal distances in equal intervals of time.
The motion of objects under the influence of gravity is an example of non-uniform motion.
Projectile Motion:
Projectile motion refers to the motion of an object thrown or projected into the air under the influence of gravity.
It follows a curved path known as a trajectory, consisting of two independent components: horizontal motion (constant velocity) and vertical motion (constant acceleration due to gravity).

Basic concepts
The document discusses key concepts in motion including point of reference, trajectory, distance, displacement, and the differences between distance and displacement. It notes that in Newtonian physics, all motion must be defined relative to a point of reference. Distance refers to the length between two points, while displacement considers both length and direction from an initial to final position. An object's distance traveled and displacement can differ, such as when running multiple laps around a track.
Motion speedandvelocity-110926010747-phpapp02
Motion is defined as the movement of an object exhibited by a change in position. Distance is the total path length traveled by an object, while displacement refers to the straight line distance between starting and end points, and has both magnitude and direction. Speed is a scalar quantity measuring how fast something is moving based on distance over time, while velocity is a vector quantity representing the rate of change of displacement over time.

salt grains to dance around. This demonstrates how vibrations can be transmitted
through a medium.
2. Emphasize that waves transfer energy and information without transferring
matter. The medium only vibrates, it does not move along with the wave.

learn best when they can observe wave phenomena.
4. Encourage students to observe waves in their daily environment - sound
waves, water waves, waves on a string. This helps make the concepts more
concrete.
5. Check for understanding by asking students to explain concepts in their own
words.

Motion in one dimension.pptx
- 1. MOTION IN ONE DIMENSION REFERENCE FRAME, POSITION, DISPLACEMENT AND DISTANCE BY KEYURI GOVENDER
- 2. Questions to make you think… 1)What is your understanding of the term “motion in one dimension”? 2) What is an example of one-dimensional motion? 3) What is your understanding of the term “position”? 4) What is the term used to describe the pathway between two points? 5) Is that the same as the difference between point A and point B ?
- 3. LEARNING OUTCOMES: • Define what one dimensional motion is • Describe the concept of a frame of reference and position • Differentiate between distance and displacement • Calculate distance and displacement in one dimensional motion • Illustrate the difference between displacement and distance
- 5. MOVEMENT IN ONE DIMENSION • Movement in one dimension refers to objects moving in a straight line. • This can be vertically up/down or left/right • Any other examples?
- 6. REFERENCE POINT AND POSITION
- 7. Reference point: is a point from which the position of an object is measured Position: is the place where an object is relative to the reference point - Symbol: x - SI unit: m - Vector - Positive or negative (relative to the reference point) A B
- 8. EXAMPLE:
- 9. Distance and displacement Displacement - Shortest distance between start and end point - Direction is measure from start to end point - Symbol: x (horizontal) y (vertical) - Vector quantity, therefore direction is important - It is measured from the start to the end point and includes direction - Vector direction can be positive or negative Distance - total length of the route - symbol: D (distance) - SI Unit: m - Scalar quantity, therefore the direction does not play a role. Thus it is always postive Distance is the length of the path followed by a moving object Displacement is the change in position with respect to the starting point
- 10. Displacement of an object is the change in its position (final position minus the initial position) Δx =x f− x i Example: Komal walks to meet Kevin at his house before walking to school. What is Komal's displacement and what distance did he cover if he walks to school via Kevin's house?
- 11. Distance (D) =path travelled =400 m+500 m =900 m Displacement (Δx)=x f − x I =−100 m + 0 m =−100 m =100 m (in the negative x direction)
