The Law of Conservation of Energy states:
Energy can created or destroyed but not transformed
Energy cannot be created or destroyed, it can only transformed
Energy can't be created, destroyed or transformed
Energy cannot be created or destroyed.
You drop a 5 kg ball from a height of 2 m. how much is the kinetic energy of the object just before it hits the ground
A 20 kg box is lifted 6 m above the ground. How much PEg does it have?
120 J
200 J
1200 J
60 J
A ball is elevated some distance off the ground. If it has a mass of 3 kg and a potential energy of 90 J, how high off the ground is the ball?
2700 m
27 m
900 m
3 m
What happens to the PEg of a rock that sits on the edge of a cliff as it starts to fall?
The rock loses PEg and gains KE.
The rock loses KE and gains PEg.
The rock retains all its PEg and gains KE
The rock retains both PEg and KE
What happens when the ball goes from the highest position to the lowest position
PE and KE increases and decreases together
Impossible to know without knowing the mass of the object
the PE decreases while KE increases
A 1.0 kg ball is stationary at the top of a hill that is 10.0 meters in height. The ball rolls all the way down the hill. What is its gravitational potential energy at the bottom of the hill?
0 joules
98 joules
49 joules
38 joules
