Question

1. What is a force? What changes can be produced by a Force? (AS)
2. Give two examples each for a contact force and a force at a distance.(As)​

Answer 1

$\huge{\underline{\mathfrak{Answer:-}}}$

1. A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.Changes that can be produced by a force are as follows: 1) Change in state of an object. 2) Change in direction of motion of an object. 3) Change in shape or size of an object.

2.These are Gravitational force (weight of a body), magnetic force. Whereas contact force is the force that acts on a body by physically coming in contact with it. For example Force of friction, Tension force, Air resistance force etc.

Answer 2

1.In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.
