Kinetic and Potential Energy

What is the difference between elastic and gravitational potential energy?

• Elastic potential energy is stored in objects that can be stretched or compressed, while gravitational potential energy is related to an object's height above the ground.

• Elastic potential energy is the energy of motion, while gravitational potential energy is the energy stored in an object due to its mass.

• Elastic potential energy is only found in rubber bands, while gravitational potential energy is found in all objects regardless of their position.

• Elastic potential energy can be converted into kinetic energy, while gravitational potential energy cannot be converted.

What is the formula for Gravitational Potential Energy?

• PE = mgh

• PE = mv^2

• PE = 1/2 mv^2

• PE = mg^2h

What is the formula for Kinetic Energy?

• KE = mv

• KE = 1/2 mv²

• KE = mgh

• KE = 1/2 mv

What is Potential Energy?

• The energy of an object in motion.

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

• The energy released during a chemical reaction.

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

What is the relationship between Kinetic and Potential Energy in a closed system?

• In a closed system, the total energy (Kinetic + Potential) remains constant, demonstrating the principle of conservation of energy.

• Kinetic energy can be converted into potential energy, but the total energy increases over time.

• Potential energy is always greater than kinetic energy in a closed system.

• Kinetic energy and potential energy are independent of each other in a closed system.

How does mass affect Kinetic Energy?

• The greater the mass of an object, the greater its Kinetic Energy, assuming the velocity remains constant.

• Mass has no effect on Kinetic Energy; only velocity matters.

• Kinetic Energy decreases as mass increases, assuming velocity is constant.

• Kinetic Energy is directly proportional to the square of the mass.

How can energy be transformed from Potential to Kinetic?

• Energy is transformed when an object falls or moves from a higher position to a lower position.

• Energy is transformed when an object is heated up.

• Energy is transformed when an object is compressed.

• Energy is transformed when an object is at rest.

What is Kinetic Energy?

• The energy an object possesses due to its motion.

• The energy stored in an object at rest.

• The energy released during a chemical reaction.

• The energy required to lift an object against gravity.

What factors affect Gravitational Potential Energy?

• The speed of the object and its color.

• The height and mass of the object.

• The temperature and pressure of the environment.

• The shape and volume of the object.

How does velocity affect Kinetic Energy?

• Kinetic Energy decreases with the square of the velocity.

• Kinetic Energy increases linearly with velocity.

• Kinetic Energy increases with the square of the velocity; if the velocity doubles, the Kinetic Energy increases by a factor of four.

• Kinetic Energy remains constant regardless of velocity.
