energy due to motion

300

the ability to cause change or do work

energy

300

what is the difference between speed and velocity?

velocity has direction, speed doesn't

speed is scalar

velocity is a vector

write the formula used to calculate work

w = f x d

300

imagine a ball rolls down a hill. does it have more kinetic energy or potential energy as it rolls down?

kinetic energy because it is moving

400

states that energy cannot be created or destroyed

law of conservation of energy
