Test- Mechanical Energy

Energy due to motion is ____________ energy. 

• Potential 
• Energy
• Kinetic
• Friction

The faster an object moves, the ________ kinetic energy it has. 

• more
• less
• none of the above
• all of the above 

As mass increases, KE ...

• increases
• decreases
• stays the same

Which has a greater impact on KE?

• mass
• velocity

The SI unit in which kinetic energy is measured is 

• Newton
• Kilogram
• Joules
• Metres per second

Rearrange the equation for kinetic energy to make mass the subject of the equation.

• m = KE/2v²
• m = 2KE/v²
• m = v²/2KE
• m = 2v²/KE

Calculate the kinetic energy of a moving 4 kg object travelling at a velocity of 3 m/s.

• 18 J
• 36 J
• 12 J
• 6 J

Energy stored by objects due to their position above Earth’s surface.

• potential energy

• kinetic energy

• gravitational potential energy

• mechanical energy

What is the unit of measurement for potential energy?

• Watts

• 5 feet high

• 10 feet high

• 15 feet high

• 20 feet high
