Question

Explain the following distance, displacement, speed, velocity, acceleration.​

Answer 1

Answer:

Speed = distance/time

Velocity = displacement/time

acceleration = the rate of change of velocity per unit of time.

Answer 2

Distance :- The total path length covered by body from initial point to final. Is called distance .

1. It can never be zero .
2. SI unit of distance is metre .

Displacement :- The shortest distance covered by body from initial point to final point is called displacement .

• it may be zero and negative .

Speed :- The rate of change of distance per unit time is called speed .

1. It is denoted by v.
2. SI unit of speed is metre per second .
3. It is a scalar quantity .

Velocity :-It is speed in particular direction .

Displacement per unit time is called velocity .

1. It is vector quantity .
2. SI unit of velocity is metre per second .

Acceleration :- The rate of change of velocity per unit time is called acceleration .

• SI unit =m per second square.
