MCQ 51: With reference to the equation of W = F.s, where 'W' is work done, 'F' is force and 's' is displacement, we can conclude that 1 Joule is equal to:

1 N m^-1, where N is Newton and m is meter
1 N m, where N is Newtons and m is meter
1 W m, where W is watts and m is meter
1 W m^-1, where W is watt and m is meter

MCQ 52: A compressed spring possesses:

Kinetic Energy
Elastic Potential Energy
Gravitational Potential Energy
Sound Energy

MCQ 53: For two objects A and B, if mass of A is same as mass of B and speed of A is twice as much as that of B, statement that is correct is:

Kinetic energy of A = kinetic energy of B; because, kinetic energy is independent of speed of the object.
since kinetic energy is inversely proportional to speed of the object, the kinetic energy of A < kinetic energy of B
Kinetic energy of A = 1 ⁄ 4 × Kinetic energy of B
Kinetic energy of A = 4 × Kinetic energy of B

MCQ 54: Capacity or ability to do work is termed as:

Power
Work
Energy
Efficiency

MCQ 55: Energy used by a moving object is termed as:

Potential Energy
Mechanical Energy
Kinetic Energy
Thermal Energy
