What is state of motion? How can a force change the state of motion.[no spam plz]

Answer 1

FORCE IS A PUSH OR PULL....

.

.

Examples- earth exerting force ...

• pushing a car..
• pulling a door

If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object. ... Thus, a force may bring a change in the state of motion of an object.

What is force?

${\tt{\red{\underline{\underline{Answer:}}}}}$

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. When the interaction ceases, the two objects no longer experience the force.

EXAMPLES FOR EFFECT OF FORCE - EXAMPLE

1) Can change the state of an object(rest to motion/ motion to rest):For example, pushing a heavy stone in order to move it.

2) May change the speed of an object if it is already moving.

3) May change the direction of motion of an object.

What is state of motion?

ANSWER

The state of motion of an object is described by its speed and the direction of motion. The state of rest is considered to be the state of zero speed. An object may be at rest or in motion; both are its states of motion.

How can a force change the state of motion?

Answer

The speed and direction of motion can be changed by applying force on an object and thus a force can bring a change in the state of motion of an object.
