I need help pls thanks you :))) 1) What is the definition of work? How does it relate to energy?

2) What are the two forms of mechanical energy we started the year studying? Define and give the equation for each.

3) Explain how a roller coaster is proof of the law of conservation of energy.

4) If a paint can weighs 50N and you lift it up 2m how much work did you do? How much
potential energy would be stored in it due to it’s position?

5) If a bowling ball that has a mass of 5Kg is moving at a rate of 15m/s how much kinetic energy does it have? If it rolled up a ramp how high would it get before it stopped?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Describe the function of the endomembrane system? what organelles are involved?
