Front

What is the tendency of an object at rest to stay at rest or an object in motion to stay in motion?

Back

Inertia

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with another surface.

Front

What is the relationship between acceleration and net force?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.
