Motion and Forces

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. (F=ma)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to gravity as the mass of two objects increases?

Back

Gravity increases.

Front

What happens to gravity as the distance between two objects increases?

Back

Gravity decreases.

Front

What is the definition of force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is the unit of force?

Back

Newton (N) is the 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 a distance-time graph?

Back

A graph that shows the distance an object has traveled over time.

Front

On a distance-time graph, which variable is on the y-axis?

Back

Distance.
