Question

Define the following:
1) Uniform motion
2)Instantaneous velocity
3)Average velocity
4)

Answer 1

hi mate⛄⛄⛄⛄

1. Uniform motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the length of the time.

2.Instantaneous velocity is the velocity of an object in motion at a specific point in time. This is determined similarly to averagevelocity, but we narrow the period of time so that it approaches zero. If an object has a standard velocity over a period of time, its average and instantaneous velocities may be the same.

3.The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, andaverage velocity can be defined as the displacement divided by the time

Answer 2

UNIFORM MOTION AND NON-UNIFORM MOTION:A body is said to be in uniform motion, if it travels equal distances in equal intervals of time.A body is said to have non-uniform motion, if it travels unequal distances in equal intervals of time.

Instantaneous velocity is the velocity of an object in motion at a specific point in time. This is determined similarly to average velocity, but we narrow the period of time so that it approaches zero. If an object has a standard velocity over a period of time, its average and instantaneous velocities may be the same.

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
