Kinetic and Potential Energy

Front

In the figure, kinetic energy is being converted into potential energy from which point? Options:

point A to point B

,

point B to C

,

The only energy involved here is kinetic energy

,

Energy is not being converted

Back

point A to point B

Front

What kind of energy is the energy in motion?

Back

kinetic energy

Front

When you are holding a book, energy is stored between the book and Earth. Which type of energy occurs on it?

Back

gravitational potential energy

Front

A moving 50 kg object has 30 Joules of KE. What is its velocity? Options: 1.0 m/s, 1.1 m/s, 1.2 m/s, 1.3 m/s

Back

1.1 m/s

Front

What will happen to the kinetic energy if the mass is doubled?

Back

Doubled

Answer explanation

The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
