Mention two kind of change that can be brought about in a body by force
force can change the shqpe of an object eg when we apply force on a lemon it squeeze
force can change the direction of an object eg when apply brakes on the car it stops

Change in momentum = mass × change in velocity
= 5kg * (0.20 - 20) m/s
= -99 kg m/s
Change in momentum of body is -99 kgm/s. Here -ve sign indicates opposite direction.
= 5kg * (0.20 - 20) m/s
= -99 kg m/s
Change in momentum of body is -99 kgm/s. Here -ve sign indicates opposite direction.
weight is given not mass
Unit is of mass. Unit of weight is Newton. 5kg is mass id
*..of the body
but may he have written wrong si unit
