Question

2 rocks of different masses roll down a hill at the same speed which rock has more kinetic energy small one or big one ???

Answer 1

The big rock will be exhibiting more kinetic energy.

Explanation:

The kinetic energy is calculated for an object with the formula of ½ mv2. Here m is the mass of the object and v is the velocity or speed of the object.

As it is known that the speed of two rocks with different masses are same so the kinetic energy will be completely depending on the mass of the object.

So the rock with higher mass will be having more kinetic energy compared to the smaller rock as its mass will be less.

So the bigger stone will be exhibiting more kinetic energy than the small one.

Answer 2

Kinetic energy depends on the mass and the speed of a moving object.

If the speeds are equal, then the rick with more mass has more kinetic energy.
