science project :– explain different types of force with examples
Answers
Answer:
Force is the external agent that produces motion or tends to produce motion or it stops motion or tends to stop motion. Basically, there are two types of forces, contact forces, and non-contact forces. Gravitational force, electric force, magnetic force, nuclear force, frictional force are some examples of force.

Answer:
Force is the push or pull on an object with mass that causes it to change its velocity.
Types of Forces
Basically, there are two types of forces: Contact forces, and Non-Contact forces. Common examples of force are:
- Gravitational force
- Electric force
- Magnetic force
- Nuclear force
- Frictional force
Explanation:
Contact forces
Those forces which represent the result of physical contact between two objects, where one of the objects exerts force on the other.
Examples of contact forces
- Stretching of the spring of a balance
- the pushing of a pram
- kicking of a football
- Pushing the door
- Hitting the ball etc are some examples of contact forces.
Types of contact forces
Some types of contact forces are given in the list below:
- Applied force
- Normal force
- Frictional force
- Tension force
- Air resistance force
- Spring force
Applied force
Force due to the action of muscles is called applied force. It is also called muscular force.
Normal force
It is a contact interaction force between surfaces. It always acts perpendicular to the surfaces and out of the surface. It comes from the microscopic deformation of molecules modeling a system of springs.
Frictional force
Frictional force comes from interactions with a surface as an object moves or tries to move relative to the surface.
Tension force
An applied force where the force is applied through a string, cable, rope, etc.
Note that a tension force can only pull, it cannot push. We usually assume the tension in a cable is the same everywhere in the cable.
Air resistance force
The force that acts in a direction opposite motion through a gas is called air resistance force. It comes from cumulative interaction with air molecules. It increases as the velocity through the gas increases. It also increases as the area normal to the direction of motion increases.
Spring force:
Spring force comes from the displacement of molecules. It is always opposite the displacement of spring.
