Amplify Forces and Motion Unit Chapters 1-4 test review

Front

What is force?

Back

A push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms or grams.

Front

How does mass affect force?

Back

Objects with more mass require a greater force to change their motion compared to lighter objects.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

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

Back

According to Newton's second law, Force = Mass x Acceleration (F = m x a).

Front

What happens to an object when a force is applied?

Back

The object will accelerate in the direction of the force, depending on its mass.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion; more massive objects have more inertia.

Front

What is the effect of a stronger force on an object?

Back

A stronger force will cause a greater change in the object's motion, resulting in higher acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction (speed with direction).

Front

What is a collision?

Back

An event where two or more objects exert forces on each other for a short time.
