Question

Differentiate between: a. distance and displacement b. speed and velocity work and power .​

Answer 1

Answer:

a. Distance and displacement

Distance :-)

1. Distance is the length of a path between two points.
2. Distance is a scalar quantity.
3. Distance is denoted by “d”.

Displacement :-)

1. Displacement is the shortest distance between two points.
2. Displacement is a vector quantity.
3. Displacement is denoted by “s”.

b. Speed and velocity

Speed :-)

1. Speed is the time rate at which an object is moving along a path.
2. Speed is a scalar quantity.
3. Formula is s= d/t.

Velocity :-)

1. Velocity is the rate and direction of an object's movement.
2. Velocity is a vector quantity.
3. Formula is d= s/t.

c. Work and power

Work :-)

1. Work is defined as the process of energy transfer to the motion of an object through the application of force.
2. Work is a scalar quantity.
3. The SI unit of work is Joule (J).

Power :-)

1. Power is defined as the amount of energy transferred in unit time.
2. Power is a scalar quantity.
3. The SI unit of power is Watt (W).
