Amplify: Forces & Motion Study Guide

Front

What is required to start moving an object?

Back

A force is required to start moving an object, and it can come from any direction.

Front

What happens to the velocity of an object when a stronger force is applied?

Back

When a stronger force is applied, there is a greater change in velocity compared to a weaker force.

Front

What is necessary to change the velocity of an object?

Back

A force is necessary to change the velocity of an object.

Front

What is the relationship between cause and effect?

Back

Cause happens first, followed by the effect.

Front

What is force?

Back

Force is a push or pull that can cause an object to move or change its motion.

Front

How does mass affect the force needed to change an object's motion?

Back

A larger mass requires a greater force to change its motion compared to a smaller mass.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).

Front

What is acceleration?

Back

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

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can slow down or stop moving objects.
