Question

a) Define the followings terms:-i) Distance ii) Displacement iii) Speed iv) Velocity v) Acceleration​

Answer 1

Answer:

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

hope this will help u..

Answer 2

☘Distance=the length of the shortest line segment joining two points. the length along a straight line or curve.

☘Displacement=the state of being displaced or the amount or degree to which something is displaced.

☘speed=the rate at which something moves, is done, or acts. physics a scalar measure of the rate of movement of a body expressed either as the distance travelled divided by average  speed or the rate of change of position with respect to time at a instantaneous speed.

☘Velocity=The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.

☘Acceleration=Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
