Motion and Forces Practice & Review

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the formula for calculating speed?

Back

Front

What does a Newton measure?

Back

A Newton is a unit of force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's 2nd Law of Motion?

Back

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What does a speed-time graph indicate?

Back

The slope of a speed-time graph indicates acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating acceleration?

Back

Front

What does it mean if an object is at a constant speed?

Back

It means the object is moving at the same speed without speeding up or slowing down.
