Forces and Motion

Front

What is a force?

Back

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

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What are balanced forces?

Back

Balanced forces are equal forces acting in opposite directions, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.

Front

What is friction?

Back

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

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

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is the role of a motor in a fountain?

Back

A motor provides a pushing force that can overcome gravity, allowing water to move up.

Front

What happens when two objects are pushed with equal force but have different masses?

Back

The object with less mass will have a greater change in motion.

Front

What is an example of a surface with high friction?

Back

A sandy beach has high friction compared to a smooth wooden board.
