Multiple Choice
Which of the following best describes the significance of studying motion with constant acceleration?
It helps us understand how objects move under uniform forces, such as gravity.
It is only useful for objects moving at a constant speed.
It is mainly used in chemistry to study reactions.
It is not relevant to real-world applications.

Which of the following best describes displacement?
A change in position having both magnitude and direction
The total distance traveled regardless of direction
The speed of an object at a given moment
The rate of change of velocity

Multiple Choice
How does the position-time graph of a car moving with constant acceleration change as time progresses?
The slope gets steeper as time goes on
The slope remains constant
The graph becomes a straight line
The graph becomes horizontal

Multiple Choice
Which of the following is the correct equation for final velocity with average acceleration?
v_f = v_i + aΔt
v_f = v_i - aΔt
v_f = aΔt
v_f = v_i × aΔt
14
15
Multiple Select
Select all statements that are true about average acceleration and its relationship to instantaneous acceleration and velocity calculations.
When acceleration is constant, average acceleration equals instantaneous acceleration.
The equation for final velocity can be used to find the time at which an object has a given velocity.
The equation for final velocity cannot be used to calculate initial velocity.
Both velocity and the time at which it occurred are needed to calculate initial velocity.

Multiple Choice
Which of the following equations can be used to relate position, velocity, and constant acceleration without including time?
v_f^2 = v_i^2 + 2a(x_f - x_i)
x_f = x_i + v_i t_f + (1/2) a t_f^2
v_f = v_i + a t_f
a = (v_f - v_i)/t
