1. This document discusses concepts related to motion including translational motion, uniform acceleration, vertical motion, freely falling objects, forces, Newton's laws of motion, impulse, momentum, velocity, and acceleration.
2. Key formulas presented include those for uniform acceleration, vertical motion, freely falling objects, Hooke's law, Newton's second law relating force and acceleration, and those relating impulse, momentum, velocity, and acceleration.
3. The document investigates the effects of forces on motion and different types of motion and forces including gravitational, electromagnetic, nuclear, and weak forces.

Motion and Forces Explained
1.
2. • Change of position in
reference to an assumed point
or center with respect to time;
a shifting movement.
3. • a motion in a straight line, circle
or circular arc, or helix (simple
motion of a clock pendulum).
4. investigates translational motion of objects
and deals with effects that forces have on
motion
m is mass of object
is velocity vector
is linear acceleration
vector
is linear momentum
vector
is force vector
5. • Uniform or constant acceleration is a type of motion
which velocity of an object changes in equal amount
in every equal time.
• Formulas used in UAM:
Vf = Vi + at
Vf² = Vi²= 2ad
a = Vi + at² or (Vi + Vf) t
2
6. • A formula used to model the vertical motion of
an object that is dropped, thrown straight up, or
thrown straight down.
Formula: y = ½ at² + v0t + y0
y = height
t = time
a = acceleration due to
gravity
v0 = initial velocity
Y0 = initial height
7. • A freely falling object is an object that moves
under the influence of gravity only.
Formula:
v = v0 – gt
y = v0t – ½ gt2
v2 = v0
2 - 2gy
8. - anything that changes or tends to change the
state of rest or motion in a body
11. • The force in a spring
or almost any other
object is
proportional to the
amount of
stretch, twist, bend
or other
displacement.
12. D. Newton’s Laws of Motion
– This law refers to the natural tendency of an
object to resist being moved, which is called
inertia. Thus mass, is a measure of inertia.
Fnet = 0 => a = 0 or v= const.
13. “The unbalanced force acting on an object
equals the object’s mass times its
acceleration.”
Fn et = ma
14. “For every action of force upon an object, that object
in return will exert an equal and opposite force upon
the other object.”
It is commonly stated as:
“for every action there is an equal or opposite
reaction”
F12 = -F21
15. E. Impulse and Momentum
–Impulse is defined as the integral of a
force acting on an object, with respect
to time.
–Impulse changes the momentum of an
object.
