Define the following terms
Answers
Answer:
Rest - a body is said to at rest if there is no change in the position with respect to time.
Motion - a body is said to at motion if the object shows change in position with respect to time.
speed - it is ratio of distance traveled to the time taken.
velocity- it is the ratio of displacement to the time taken.
1.Rest: An object is said to be at rest if it does not change its position with respect to its surroundings with time.
2.Motion, in physics, change with time of the position or orientation of a body.
3.speed- Speed can be thought of as the rate at which an object covers distance.
4.Velocity - the speed at which something moves in a particular direction
5.uniform motion - if an object is travelling with uniform motion, it is moving in a straight line at a constant speed.
6.non uniform motion- This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
7.mass- Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.
8.weight- a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
