Front

How is force measured?

Back

Force is measured in Newtons.

Front

What is balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to move or change direction.

Front

What is motion?

Back

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

Front

If a swimmer moves at a speed of 2.0 meters/second, how long will it take to swim 100 meters?

Back

It will take 50 seconds.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy, while kinetic energy is the energy of motion.

Front

What is gravity?

Back

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