Total energy in a closed system will always change with the motion of an object.
True; energy is destroyed due to friction
False; energy cannot be destroyed, only transferred.
What is the equation for kinetic energy?
KE = 1/2 Mass X Velocity squared
KE = Speed (m/s) + height (m)
KE = Distance (m) / time (s)
KE = Mass (g) * gravity * height (m)

What is the gravitational potential energy equation (weight = mass X acceleration due to gravity)?
PE = mass X velocity
PE = weight X speed
PE = weight X height
PE = height X weight
Which of the following has the GREATEST IMPACT on the kinetic energy of an object and why?
Mass because very small and very large things can't have the same kinetic energy.
Velocity because its value is squared.
Height because it can be a very large number.
The acceleration due to gravity because it is acceleration which is more than velocity.
The acceleration of an object due to gravity on Earth is:
The same as its velocity
9.8 m/s2
It depends on the mass of an object
Equal to its kinetic energy
