Question

what can a force do?what can a Force 2

Answer 1

Answer:

* Vector quantities are expressed in magnitude as well as the direction of the object. E.g: Velocity, displacement, weight, momentum, force, acceleration etc.

* Vectors are used to find the resultant component acting on a body.

* When multiple forces act on a body, they can be resolved into one component known as the net force acting on the object.

Answer 2

Force acting on a body can change its state of rest or motion, speed, direction of motion of object, shape, size.

$\sf{ \pink{\Huge{More:-}}}$

The force cannot be seen or felt but can be explained on the basis of effects caused by it.

Force as that external push or pull acting on an object which changes or tends to change the state of rest for the state of uniform linear motion of an object. A force may also deform an object.

Pressure:-

Force acting normally on a unit surface area is called pressure. Liquid and gases exert pressure in all directions.

Turning effect of force:-

A force is associated with translation motion in which an object moves as a whole along a given path. However, under suitable conditions, A force can turn an object about a given axis. This is known as turning effect of force.

Example:-

♦ When you apply force on the handle of a door, the door turns around the hinges.

♦ When a driver applies a force on the steering wheel of his car, it causes turning effect on the wheel.
