Question

pls help !!!!!!!!!!!!!​

Answer 1

$\huge\tt\pink{Answer}$

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

In the world of mechanics, there are four basic types of motion.

2. The rate of change of position of an object in any direction.

3. The rate of change of the object’s position with respect to a frame of reference and time.

4. m/s.

5. ☀︎︎UNIFORM MOTION☀︎︎

★Uniform motion has zero acceleration.

★The uniform motion is identical to the actual speed of the object.

★Uniform motion covers equal distance at an equal time interval.

★In uniform motion, the distance to time graph shows a straight line.

☀︎︎NON-UNIFORM MOTION☀︎︎

★The non-uniform motion has non-zero acceleration.

★The non-uniform motion is different from the actual speed of the object.

★Non-uniform motion covers unequal distance at equal time interval.

★In non-uniform motion, the distance to time graph shows a curved line.

5. Speed.

Answer 2

Explanation:

1.An object is said to be in motion if it changes its position with respect to its surrounding in given time

periodic , rectilinear, circular rotational, curvilinear,translatory, oscillatory

2.Speed is a scalar quantity it is the magnitude of the velocity

3.Velocity is a vector quantity when velocity is given we must specify the magnitude and the direction of travel

4.m/s

5.uniform motion:when a body covers equal distance in a straight line in equal intervals of time however small these intervals may be

Non uniform Motion:when a body covers unequal distance in equal intervals of tine in a straight line.

6.speed
