Car mass is 1200 kg moving velocity is 108 km/hr. On applying brakes velocity reduced to 36 km/hr. Find change in momentum?
(posted by Aditi)
Answer: m=1200 kg
u=108 x 5/18=30m/s
v=36×5/18=10m/s
Change in momentum = m(v-u) = 1200 x (30-10)=1200 …

Explain IMPULSE in simple terms
Vimal asked this question. Impulse is the effect of a force and is measured as the change in momentum produced. The same effect, that is the same change in momentum can be produced by a large force acting for a short interval of time, a small force acting for a large interval of time or a moderate […]

How to describe momentum physically ?
Kiran asks: “How do you describe momentum physically by not in definitions like product of mass and velocity?” Answer: Momentum is defined as “Mass in Motion” or “The quantity of motion“. Momentum is a measure of the “effect” a moving body can produce. It is a measure of the “effort” required to bring a body to […]
