Question

define motion. define motion. ​

Answer 1

Answer:

Defining Motion.

Explanation:

Motion is the phenomenon in which an object changes its position.

• Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
• The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame with a change in time.
• Motion applies to various physical systems: to objects, bodies, matter particles, matter fields, radiation, radiation fields, radiation particles, curvature, and space-time. One can also speak of the motion of images, shapes, and boundaries.
• If an object is not changing relative to a given frame of reference,             the object is said to be at rest, motionless, immobile, stationary, or to have a constant or time-invariant position concerning its surroundings.

• Laws of motion-
• First law/law of inertia- Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
• Second law- Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
• Third law- Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
