How Many Types Of Forces Are There

There are two methods to apply force to an item: by making contact with the object or avoiding contact with it. There are two different types of forces as a result:

1. Contact forces

2. Non-contact forces

Contact Forces

A force that has to touch an object to exert a force on it is known as a contact force. Because contact is made in either scenario, kicking a ball and closing a door are both examples of contact forces.

Additional classifications include, they are:

1. Frictional force

2. Applied force

3. Normal force

4. Frictional Force

A soft kick causes a ball to roll across the ground. At that point, a force applies in the opposite direction to the way the ball is travelling, ultimately causing the ball to stop. Frictional force is the name given to this kind of force. When an object's surface comes into touch with the surface of another object, it typically resists the motion of the object.

2. Applied Force

When a person or something exerts a force on another object, which causes the object to move, It is known as the applied force.

3. Normal Force

The force applied to stop solid objects from passing through one another is known as the normal force. A contact force is a regular force. A typical force cannot be applied between two surfaces that are not in contact.

Non-Contact Force

A force applied without making contact is known as a non-contact force. Two further classifications are made for it.

They are

1. Magnetic force

2. Gravitational force

3. Gravitational Force

The gravitational force is the attraction between any two mass-containing objects. It is a result of nature. There is always an attractive force between stars, planets, and galaxies. Gravity gives things on Earth weight, and the moon's gravity causes the tides in the ocean.

2. Magnetic Force

A magnetic force is described as a force that is applied between two magnet poles as well as moving electrically charged particles. It can be either attractive or repulsive.

Effects Of A Force

• When an object experiences a force while in motion, the object may become immovable as a result of the applied force.

• When an item is at rest and is exposed to a force, the object may move as a result of the applied force.

• A force given to an item might cause it to move more slowly.

• When a force is applied, the object's speed can also be increased by the force.

• The movement direction of an object can also be altered by the force being applied to it.

• An object's size and shape can also be altered by force.

Conclusion Of A Force

By definition, force is just an object being pulled or pushed. It is an agent that has the ability to alter the shape or size of the item under consideration as well as its movement by slowing it down, preventing it from travelling, or changing its direction. The acceleration or degree of change is used to calculate additional force. The SI unit of force is Newton, and depending on whether two bodies or surfaces come into touch with one another, they may be divided into two categories: contact force and non-contact force.

Examples

Examples of contact force

• A fire can be started without a match by rubbing two pieces of wood together.

• Pulling out a desk chair with your hand to take a seat.

• Opening a jar by twisting the lid.

• A water glass was placed on a table.

• Food containers resting on a refrigerator shelf.

Examples of Non-contact force

• The Earth and other planets maintain a constant distance from the sun

• When anything is tossed up, it usually falls back toward the ground.

• When fruit detaches from a tree, it drops to the ground.

• A compass points north as a result of the magnet's attraction to the Earth's south pole.

• A motor that rotates as a result of magnetic interactions on each side of the centre.
