Question

Match the following.

Column A	Column B
a. Force	i. Hydro electricity
b. Flow water	ii. Gravitational force
c. Photosynthesis	iii. Push or pull
d. Earth's force	iv. Frictional force
e. Opposes motion	v. Solar energy

Accepted Answer

a-iii

The push or pull on an object is called force, and it changes its position or shape.

b-i

The electricity produced by the energy of the flowing water is known as hydro electricity. Water that flows down a hill has enough energy to turn the huge turbines of the generators, to generate the electricity.

d-ii

The force with which the earth pulls all the objects downwards or towards itself is known as gravitational force.

e-iv

Frictional force is the force that opposes the movement of an object over another. This force is less on a smooth surface and more on rough surfaces.

Column A Column B

a. Force iii. Push or pull

b. Flow water i. Hydroelectricity

c. Photosynthesis v. Solar energy

d. Earth's force ii. Gravitational force
