Question

Define the following terms:
1. Uniform Motion
2. Non-uniform motion
3. Distance
4. Displacement
5. Motion
6. Rest
7. Scalar
8. Vector
​

Answer 1

Answer:

1.When a body covers equal distances in a straight line, equal intervals of time are called uniform motion.

2.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.

3.Distance is the total movement of an object without any regard to direction.

4.Displacement is the change in position of an object. It is a vector quantity and has a direction and magnitude.

5.We can define motion as the change of position of an object with respect to time.

6.An object is said to be at rest if it does not change its position with respect to its surroundings with time.

7.Scalar quantity is defined as the physical quantity with magnitude and no direction.

8.A vector quantity is defined as the physical quantity that has both direction as well as magnitude.
