Question

pls answer it''

(b) Define Kinetic energy . On what factors does it depend.
(c) Write four differences between mass and weight

Answer 1

Answer:

b) Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. ... And for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen. The kinetic energy is dependent upon the square of the speed.

c) Weight is dependent on gravity and so, it varies from place to place. Weight can be zero where there is no gravity (like space).

The value of the mass remains constant.The value of weight varies according to the position of an object.Mass is the scalar quantity and weight is a vector quantity. The unit of mass is kg while the unit of weight is N. Mass can't be changed by changing place, weight can be changed by changing the place.

Answer 2

Answer:

Kinetic energy

Explanation:

Kinetic energy - the energy possesd by the body while moving.

It depends on mass and the square of velocity of the bod

Difference between mass and weight

1 Mass is the measure of inertia and weight is the Measure of pulling force of gravity.

2. Mass is a scalar quantity and weight is a vector quantity.

3. Mass has a unit kg and weight has a unit N

4. Mass can't be changed by changing place but weight can be.
