(a) a bullet fired from a gun.
(b) the wound up spring of a toy car.
(c) the water, stored at a height, in a tank.
(d) a moving bus.​

Answer 1

Answer:

a) kinetic energy

b) potential energy

c) potential energy

d) kinetic energy

Answer 2

(a) Kinetic energy

(b) Mechanical energy due to position

(c) Potential energy due to position

(d) Potential to position.

Explanation:  

• The type of ‘energy possessed’ by an object due to its configuration is known as the mechanical energy. Mechanical energy is due to the rest and is known as the kinetic energy.  

• The kinetic energy due to the position of the object is known as the potential energy.  

• The ‘energy stored’ in a spring is known as the spring potential energy.
