Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.

* When we apply force in the same direction, it adds to one another. When we apply force on an object from two different directions then it creates a difference between the two forces.
There are different forms of forces:

A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interactionn

Magnetic force is a type of force between two objects that contain a magnetic field. These objects can be magnets or objects containing magnetic material. The force of attraction or repulsion between objects depends on the type of magnetic material.

An apple falling down from a tree is one of the best examples of non-contact force. Iron pins attracted in the presence of a magnet bar without any physical contact. Falling raindrops on earth is also an example of a non-contact force. The charging of the hair and attraction of paper bits towards it. Two magnets placed close to each other are also a non-contact force example.

Answer: (a) Agents are fingers, object is lemon, effect of force changes the shape of lemon. (b) Agents are fingers of the person squeezing the tube, object is toothpaste tube and effect of the force can be observed as the paste coming out of the tube (change in shape). (c) Agent is the load suspended, object is the spring and effort can be seen in the form of elongation of spring on suspension of load (change in shape). (d) Agent is muscles of athlete, object is athlete himself and effect of the force changes the state of motion of the athlete

A rocket has been fired upwards to launch a satellite in its orbit. Name the two forces acting on the rocket immediately after leaving the launching pad. Answer: The forces that act when a rocket leaves launching pad are as follows: (i) Gravitational force of the earth (downward) (ii) Frictional force of air (in opposite direction)

Force is the push or pull applied to an object to make it move or accelerate. Pressure is a measure of the force per unit area that is applied to an object. Force and pressure can be used to explain everyday phenomena such as wind, water flow and air pressure.

A force is also known as a 'push' or 'pull' and is measured in Newtons (N). Pressure is the force per unit area and is measured in Pascals (Pa). The pressure caused by a human finger is enough to make a dent in an apple.
