Forces Check-in

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

How does mass affect speed?

Back

Increasing mass generally decreases speed when the same force is applied, as more force is needed to move a heavier object.

Front

What happens to the speed of an object when it loses mass?

Back

The speed of an object may increase when it loses mass, as less force is needed to move it.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is the effect of a smoother surface on motion?

Back

A smoother surface reduces friction, allowing objects to move faster.

Front

What is the role of gravity in falling objects?

Back

Gravity pulls objects toward the ground, causing them to fall.

Front

How can you increase the speed of a rolling object?

Back

You can increase the speed by reducing friction or increasing the incline of the surface.
