Question

what is force?
what are the types of force ? what is the units of force ?
what is the dimensions of force?​​

Answer 1

Explanation:

1)Action-at-a-Distance Forces. Frictional Force. Gravitational Force. Tension Force. Electrical Force.

list below.

2)a Applied Force

b Gravitational Force

c Normal Force

d Frictional Force

e Air Resistance Force

f Tension Force

g Spring Force

3)The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg.

4) The dimension of force, another derived unit, is the same as the dimension of mass times acceleration, and hence the dimension of force is [MLT−2].

☞ A push or pull is considered as force.

☞ There are 2 types of forces

1. Contact Forces→ Forces that act on a body either directly or through a medium are called contact forces. e.g

• Muscular Force
• Mechanical Force
• Frictional Force

2. Non-Contact Forces→ Forces that act through spaces without making direct contact with the body are called non-contact forces. e.g

• Gravitational Force
• Electrostatic Force
• Magnetic Force

☞ SI Unit→ Newton (N)

☞ Dimension→ LMT^-2
