Potential and Kinetic Energy

What is an example of an object with both Potential and Kinetic Energy?

• A pendulum has potential energy at its highest point and kinetic energy at its lowest point.

• A rock sitting on a cliff has only potential energy.

• A car moving at a constant speed has only kinetic energy.

• A stretched rubber band has only potential energy.

Example of Kinetic Energy in everyday life?

• A car driving down the road has kinetic energy due to its movement.

• A book resting on a table has kinetic energy.

• A person standing still has kinetic energy.

• A ball thrown in the air has kinetic energy.

What is gravitational potential energy?

• The energy an object has due to its motion.

• The potential energy an object has due to its height above the ground and the force of gravity acting on it.

• The energy stored in an object due to its temperature.

• The energy released when an object falls to the ground.

How does speed affect Kinetic Energy?

• Kinetic energy decreases with the square of the speed.

• Kinetic energy increases linearly with speed.

• Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

• Kinetic energy remains constant regardless of speed.

What is the formula for Kinetic Energy?

• KE = mv

• KE = 1/2 mv

• KE = 1/2 mv²

• KE = mv²/2

What type of energy does a compressed spring have?

• Kinetic energy due to motion

• Thermal energy from heat

• Potential energy due to its position

• Chemical energy stored in bonds

What happens to Potential Energy when an object falls?

• It increases as the object falls.

• It remains constant throughout the fall.

• It decreases while kinetic energy increases.

• It becomes zero when the object hits the ground.

What type of energy does a moving bicycle have?

• Potential energy

• Kinetic energy

• Thermal energy

• Chemical energy

How does height affect Potential Energy?

• The higher an object is, the more potential energy it has, because potential energy is directly proportional to height.

• Height has no effect on potential energy.

• Potential energy decreases as height increases.

• Potential energy is inversely proportional to height.

What is the formula for Potential Energy?

• PE = mgh

• PE = mv^2

• PE = 1/2 kx^2

• PE = Fd
