Force & Motion Test Study Guide

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

What unit is force measured in?

Back

Newton's (N)

Front

What does Newton's 1st Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

If a polar bear swims at an average speed of 2.6 m/s for 120 seconds, how far does it travel?

Back

312 m

Front

What happens to an object moving at a constant speed?

Back

The object maintains the same speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between force, mass, and acceleration according to Newton's 2nd Law?

Back

Force = Mass × Acceleration (F = ma)

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth.

Front

What is deceleration?

Back

Deceleration is a decrease in the speed of an object.
