Force and Motion 1 (Introduction to Force and Motion)

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is mass?

Back

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

Front

What is momentum?

Back

The quantity of motion an object has, which depends on its mass and velocity.

Front

How does mass affect motion?

Back

Heavier objects require more force to move the same distance as lighter objects.

Front

What happens when a force is applied to an object at rest?

Back

The object will start to move in the direction of the applied force.

Front

What is the relationship between force and motion?

Back

Force causes changes in motion; without force, an object at rest stays at rest.

Front

What is an example of an object in motion?

Back

A soccer ball rolling across the field after being kicked.
