Front

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 gravity?

Back

A force that pulls objects toward each other, especially the pull of the Earth on objects.

Front

What is friction?

Back

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

Front

What happens when two forces are applied to an object in the same direction?

Back

The forces combine to create a greater force.

Front

What happens when two forces are applied to an object in opposite directions?

Back

The forces cancel each other out, resulting in no movement if they are equal.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to move it.

Front

How can you reduce the amount of force needed to move an object?

Back

By reducing the mass of the object or using tools like ramps or levers.

Front

What is inertia?

Back

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

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.
