Energy Review

Which answer best describes potential energy?

• stored energy

• energy of motion

• energy of chemicals

Which TWO characteristics affect the amount of POTENTIAL energy an object has?

• mass

• weight

• speed

• height above the ground

Which answer best describes kinetic energy?

• stored energy

• energy of motion

• energy of chemicals

Which TWO characteristics affect the amount of KINETIC energy an object has?

• mass

• weight

• speed

• height above the ground

At what point does the cart have the MOST gravitational potential energy?

• a

• b

• c

• d

WHY does point a show the most GPE?

• Because the cart is going downhill

• Because the cart is showing its max speed

• Because the cart is at its lowest point

• Because the cart is at its highest point

At what point is the cart showing the MOST kinetic energy?

• a

• b

• c

• d

Select TWO reasons why point c shows the most KE.

• Because the cart is going downhill

• Because the cart is showing its max speed

• Because the cart is at its lowest point

• Because the cart is at its highest point

WHY does point d show less GPE than point a?

• Because the cart has more speed at point a

• Because the cart has less height off the ground at point a

• Because the cart has more mass at point a

• Because the cart has the most height off the ground at point a

Which option best describes mechanical energy?

• elastic + chemical energy

• gravitational + chemical energy

• potential +kinetic energy
