Potential and Kinetic energy

How does height affect potential energy?

• The higher an object is, the more potential energy it has because it has the potential to fall further.

• Height has no effect on potential energy.

• Potential energy decreases as height increases.

• Potential energy is only affected by the mass of the object.

What is the formula for gravitational potential energy?

• PE = mv^2

• PE = mgh

• PE = 1/2 mv^2

• PE = mg^2h

When is kinetic energy at its maximum?

• When an object is at rest.

• When an object is moving at its highest speed.

• When an object is moving at a constant speed.

• When an object is falling freely.

How do potential and kinetic energy transform into each other?

• Potential energy can transform into kinetic energy when an object is lifted.

• Kinetic energy can transform into potential energy when an object falls.

• Potential energy can transform into kinetic energy when an object falls, and kinetic energy can transform into potential energy when an object is lifted.

• Potential energy and kinetic energy cannot transform into each other.

What is the relationship between mass and kinetic energy?

• Kinetic energy decreases with mass; if the mass of an object doubles, its kinetic energy halves if the velocity remains constant.

• Kinetic energy increases with mass; if the mass of an object doubles, its kinetic energy also doubles if the velocity remains constant.

• Kinetic energy is independent of mass; changes in mass do not affect kinetic energy at all.

• Kinetic energy increases with mass; if the mass of an object doubles, its kinetic energy quadruples if the velocity remains constant.

What is kinetic energy?

• The energy of an object at rest.

• The energy of an object in motion.

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

• The energy released during a chemical reaction.

What is potential energy?

• The energy stored in an object due to its position or state.

• The energy of motion in an object.

• The energy released during a chemical reaction.

• The energy required to change the temperature of an object.

When is potential energy at its maximum?

• When an object is at its highest point.

• When an object is in motion.

• When an object is at rest on the ground.

• When an object is falling down.

What is the formula for kinetic energy?

• KE = mv

• KE = 1/2 mv²

• KE = mgh

• KE = 1/2 mv

What factors affect gravitational potential energy?

• The color of the object and its mass

• The height of the object above the ground and its mass

• The temperature of the object and its volume

• The shape of the object and its density
