1) Kinematics in two dimensions involves calculating displacement, velocity, and acceleration based on an object's initial position, velocity, acceleration, and time. Projectile motion can be analyzed by separating the horizontal and vertical motions.
2) For projectile motion, the horizontal velocity remains constant while the vertical velocity is affected by gravity. Objects thrown at an angle will hit the ground at the same time due to their downward acceleration.
3) The maximum range of a projectile is achieved at a launch angle of 45 degrees. Range can be calculated using the initial velocity, launch angle, and gravitational acceleration.
Hello! This is my PowerPoint Presentation on free falling bodies.
Some transition might failed when viewing. so if you want a better presentation using this, you could ask me.
The Galileo vs Aristotle part is kind-of a video presentation. You could find a better video on Youtube.
For further question, just comment on the comment box below.

A projectile is an object upon which the only force acting is gravity. There are many examples of projectiles. An object dropped from rest is a projectile as long as that the influence of air resistance is negligible. An object that is thrown vertically upward is also a projectile provided that the influence of air resistance is negligible. And an object which is thrown upward at an angle to the horizontal is also a projectile as long as that the influence of air resistance is negligible. A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
Describes displacement, velocity, acceleration as vectors and distance and speed as scalars, Show all needed equations and their use.

Solving AIEEE problems fast is fun. We claim that 30% of AIEEE problems consists of such problems only and show you how to save your time for the problems where you may be losing double of your time. All you need to know is aware of these tricks
A PowerPoint made by me. It covers all the Motion related topics. Revised edition will be established on the 14th October 2015.

Uniformly Accelerated Motion and Free Fall Motion_NOTES.pptxALVINMARCDANCEL2
An object is in Free-Fall when the only force acting on the object is the Force of Gravity, however, we haven’t defined
Force much less the Force of Gravity, so, until we have defined the Force of Gravity, we have a slightly different definition.
An object is in Free-Fall when:
- It is not touching any other objects♥
- There is no air resistance (it’s in the vacuum we can breathe)
We are now in the vacuum that we can breathe and will be for the remainder of this class, unless otherwise stated.
Common Misconception: For some reason people think the word “fall” in Free-Fall means that the object must be going
down. This is absolutely, not true. An object thrown upward is in Free-Fall from the moment it leaves the persons hand
until it touches the ground.
This slide covers the entire contents for the unit of Projectile motion as described by NTA level 4 curriculum for Geology and Mineral Exploration in mines, Mineral Processing Engineering, Environmental Engineering in Mines and Petroleum Geo sciences at Dodoma Polytechnic of Energy and Earth Resources Management.

3. a = g W W W Projectile Motion A projectile is a particle moving near the Earth’s surface under the influence of its weight only (directed downward). Projectile motionis a combination of horizontal and vertical motions.
4. Consider Projectile at an Angle: vo voy q vox A red ball is projected at an angle q. At the same time, a yellow ball is thrown vertically upward and a green ball rolls horizontally (no friction). Note vertical and horizontal motions of balls
5.
6. W W Vertical and Horizontal Motion Simultaneously dropping a yellowball and projecting a red ball horizontally. Why do they strike the ground at the same time? Once motion has begun, the downward weight is the only force on each ball.

9. 1.2 m 2.0 m Example 1:A ball rolls off the top of a table 1.2 m high and lands on the floor at a horizontal distance of 2.0 m. What was the velocity as it left the table?
11. Example 2: The best leaper in the animal kingdom is the puma, which can jump to a height of 12.00 ft when leaving the ground at an angle of 45.0o. With what speed must the animal leave the ground to reach that height? How far has the puma leaped from its starting point?
12. Example 3: Karl, who is a 2.00-m basketball player, is standing on the floor 10.0 m from the basket. If he shoots the ball at a 40.0o angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket from the ground is 3.05 m.
13. Relative velocity Relative velocity is all about relating measurements of two different observers, one moving with respect to the other. Measurements of velocity depend on the reference frame (coordinate systems) of the observers.
14. Problem Solving Strategy Label each object involved with a letter that reminds you of what it is (for example, E for earth). Look through the problem for phrase such as “The velocity of A relative to B,” and write the velocities as 𝑣𝐴𝐵; When a velocity is mentioned but it isn’t explicitly stated as relative to something, it’s always relative to earth. Take the three velocities you’ve found and assemble them into an equation: 𝒗𝑨𝑩=𝒗𝑨𝑬−𝒗𝑩𝑬. There will be two unknown components. Solve for them with the x- and y-components of the equation developed in step 3.
15. Example 1: The boat is heading due north as it crosses a wide river with a velocity of 10.0 km/h relative to the water. The river has a uniform velocity of 5.00 km/h due east. Determine the velocity of the boat with respect to an observer on the riverbank.
16. Example 2: A train is traveling with a speed of 15.0 m/s relative to earth. A passenger standing at the rear of the train pitches a baseball with a speed of 15.0 m/s relative to the train off the back end, in the direction opposite the motion of the train. What is the velocity of the baseball relative to earth?
