Kinematics
A car travels 500m from rest and with an final velocity of 55 m/s. What was its acceleration?
3.03 m/s^2
0.11 m/s^2
6.05 m/s^2
0.06 m/s^2
Which scenario demonstrates an example where instantaneous velocity is zero but acceleration is not?
Hockey puck sliding across ice coming to natural rest without external forces applied other than friction.
A ball at its highest point when thrown straight up into the air before it starts falling back down.
Car parked on a flat road with engines turned off.
Satellite orbiting Earth in uniform circular motion at constant speed along its path.
If two billiard balls collide elastically on a pool table, what happens to their total momentum after the collision?
It decreases only if they stick together.
It increases.
It changes direction but stays the same magnitude.
It remains constant.
On an acceleration vs. time graph for an object moving in one dimension, what does an area below the time-axis between two points in time represent?
The distance traveled by the object over that period of time.
The total displacement experienced by the object since it started moving.
The increase in object's velocity over that period of time.
The decrease in object's velocity over that period of time.
If a car moving in a straight line steadily increases its speed every second, which graph best represents its acceleration over time?
An upward sloping line above the time axis.
A horizontal line above the time axis.
A downward sloping line above the time axis.
A horizontal line below the time axis.
What does a velocity-time graph with a horizontal line above the time axis represent?
Constant positive velocity
Object at rest
Decelerating motion
Accelerating motion
How does increasing mass affect gravitational force between two objects where all other factors remain unchanged?
Gravitational pull becomes zero as one object’s mass becomes significantly higher than that of another object’s mass.
Gravitational force decreases inversely with increased mass due to dilution effects.
Gravitational force increases directly with greater mass of either object involved.
Mass has no effect on gravitational attraction if distances remain consistent between objects.

A student throws a ball upwards; which statement best describes the ball’s motion after leaving her hand but before returning?
The ball slows down until it stops momentarily at its highest point then begins to fall back down.
There is no vertical component of acceleration while the ball travels upwards.
Ball continuously speeds up until caught again by the student.
Ball maintains a steady speed throughout until caught again by the student.
What happens when two skaters standing still on ice push against each other?
The skater who is heavier stays still while the lighter skater moves away.
They move away from each other in opposite directions.
Friction causes them to slip at different angles depending on their weights.
Both skaters experience equal backward velocities regardless of weight differences.
If a car is moving at a constant speed in a straight line, what is its acceleration?
Zero
Increasing over time
Equal to its velocity
Constant but not zero
