Front

What is the unit of force?

Back

Newton (N) is the unit used to measure force.

Front

What are balanced forces?

Back

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate or change direction.

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

How does mass affect weight on different planets?

Back

Weight changes with gravity, so an object will weigh less on the Moon than on Earth due to its smaller mass.
