Question

7. Define (i) speed
(iv) displacement
(ii) velocity
(iii) acceleration
(iv)displacement​

Answer 1

Answer:

1. Speed can be thought of as the rate at which an object covers distance. ... Speed has the dimensions of distance divided by time. The SI unit of speed

4.the action of moving something from its place or position.

2.the speed of something in a given direction

3. Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always

Answer 2

Explanation:

speed : Speed is defined as the rate of movement of a body expressed either as the distance travelled divided by the time taken or the rate of change of position with respect to time at a particular point.

displacement :Displacement is a vector quantity that refers to the shortest distance between the two positions of the object i.e, the difference between the final and initial positions of the object, in a given time.

velocity: Velocity is the vector quantity that refers to “the rate at which an object changes its position.”

acceleration : The rate of change in velocity is defined as acceleration. Therefore, “The rate of change of velocity of an object with respect to time is known as acceleration.”
