Amplify: Forces & Motion Study Guide

Front

What is force?

Back

A push or pull that can cause motion.

Front

What direction must a force come from to stop an object in motion?

Back

The opposite direction as the object's motion.

Front

What is the relationship between cause and effect?

Back

Cause happens first, followed by effect.

Front

What direction must a force come from to start an object moving?

Back

Any direction.

Front

What is the difference between speed and velocity?

Back

Speed is the rate of motion, while velocity includes direction.

Front

What is Newton's First Law of Motion?

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 inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of objects and can cause them to slow down or stop.
