Kinematic equations can only be used for problems with constant ....

• Position

• Velocity

• Acceleration

• Time

• Variables

In a normal environment, why does a bowling ball and feather hit the ground at different times when dropped from the same height?

• They don't; they hit the ground at the same time.
• One is more dense than the other.
• One is heavier than the other.
• Air resistance 

What happens to the velocity of a ball as it is dropped off a cliff?

• It decreases at a uniform rate

• It increases at a uniform rate

• It is constant

• It increases at a non-uniform rate

The gravitational acceleration of an object in a vacuum near the surface of the Earth is defined as:

• g = 9.8 m/s.

• g = 9.8 m.

• g = 9.8 m/s².

• g = 9.8 s.

When an object falls, ______________________________.

• It accelerates at a constant rate until it hits the ground

• It accelerates at a non-constant rate until it hits the ground

• It accelerates at a constant rate until it reaches terminal velocity

• It accelerates at a non-constant rate until it reaches terminal velocity

Product of mass of body and acceleration is called

• Displacement

• Force

• Load

• Momentum

When an object resists change, like a body in a turning car, it is called ________________.

• inertia

• force

• friction

• drag force

For every action, thereʼs an equal and opposite reaction. *Action-Reaction*

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• force

A force that results from two objects rubbing past each other.

• Gravity
• Friction
• Inertia
• Force

The force that pulls objects towards Earth.
