Question

what is motion in detail​

Answer 1

In physics, the motion is the change in position of an object with respect to its surroundings in a given interval of time. The motion of an object with some mass can be described in terms of the following:

distance

displacement

speed

velocity

time

acceleration




Types of Motion in Physics

Motion of an object depends on the type of force acting on the body. Examples of different kinds of motion are given below.

Translational – It is the type, where an object moves along a path in any of the three dimensions.

Rotational – It is the type, where an object moves along a circular path about a fixed axis.

Linear – It is a type of translational motion where the body moves in a single direction along a single dimension.

Periodic – It is the type of motion that repeats itself after certain intervals of time

Simple Harmonic – It is the type of motion like that of a simple pendulum where a restoring force acts in the direction opposite to the direction of motion of the object. This restoring force is proportional to the displacement of the object from mean position.

Projectile – It is the type of motion which has a horizontal displacement as well as vertical displacement.

Oscillatory – It is the type of motion which is repetitive in nature within a time frame. If it is mechanical in nature it is called vibration.



Laws of Motion

Newton’s Laws of Motion laid the foundation for classical mechanics today. Although subject to minor limitations, these laws of motion are valid everywhere and are therefore used. The laws are given as stated below in a brief description

First Law: Any object will continue to remain in its existing state of motion or rest unless a net external force acts on it.

Second Law: If an object has a certain mass, greater the mass of this object, greater will the force required be to accelerate the object. It is represented by the equation F = ma, where ‘F’ is the force on the object, ‘m’ is the mass of the object and ‘a’ is the acceleration of the object.

Third Law: For every action, there is an equal and opposite reaction.

Answer 2

Answer:

Explanation:

In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
