Transport: Movement means Energy

• energy is changed from one form to another during a vehicle's motion.
• the total amount of energy remains constant.
• energy can neither be created nor destroyed

a measure of the energy transferred during an energy transformation

the rate at which energy is transferred during an energy transformation

the change in gravitational potential energy of an object is the work done against gravity or by gravity

the energy an object has due to its motion

• both its mass and speed
• increasing the mass and/or the speed of the object increases its kinetic energy

the total amount of energy stays the same
