Front

Which unit is equivalent to a Joule?

Back

Newton-meter (N·m)

Front

What type of energy is known as the energy of motion?

Back

Kinetic energy

Front

True or False: If the distance an object moves is zero, the work done on the object is also zero.

Back

True

Front

If 150 Joules of work is done to move a box 10 meters, what is the net force applied?

Back

15 N

Front

How does doubling the velocity of an object affect its kinetic energy?

Back

The kinetic energy is quadrupled.

Front

What is the formula for calculating work?

Back

Work = Force × Distance (W = F × d)

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 0.5 × Mass × Velocity² (KE = 0.5 × m × v²)

Front

What is potential energy?

Back

Energy stored in an object due to its position or state.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy.
