Two objects are moving at the same speed. Which one has more kinetic energy?
the object that is higher above ground level
the object with the greater mass
the object that is made of more dense material
the object with the greater volume
3 answers
The object with the greater mass would have more kinetic energy. Kinetic energy is directly proportional to an object's mass, so the object with a larger mass would have more kinetic energy, regardless of other factors such as height, density, or volume.

Correct
1.Which falling object will result in the least kinetic energy when it collides with the ground?
100 grams of dirt falling at 15 m/s
10 grams of dirt falling at 2 m/s
Correct
10 grams of water falling at 1 m/s
100 grams of water falling at 10 m/s
2.Two objects are moving at the same speed. Which one has more kinetic energy?
the object that is higher above ground level
Correct
the object with the greater mass
the object that is made of more dense material
the object with the greater volume
3.Which scenario has a greater speed?
Scenario 2
Correct
Neither because the trucks are each moving at the same speed.
Scenario 1
4.In which scenario is the kinetic energy the greatest?
Scenario 2
Neither because the kinetic energy is the same in both scenarios.
Correct
Scenario 1
5.Which rider has more kinetic energy and why?
Nathan has more kinetic energy because he is going faster.
Correct
Nathan has more kinetic energy because he has more mass.
They have the same amount of kinetic energy because they are going the same speed.
Isabella has more kinetic energy because she has less mass.
Because they are biking at the same speed, the difference in their kinetic energies depends on the difference in their masses. Nathan has more mass than Isabella, which means he has more kinetic energy.
