Why Does The Big Car Has A Greater Momentum?
Why does the big car has a greater momentum?
Good Day
Momentum is the tendency of an object to continue moving. The mathematical formula of momentum is (momentum = mass × velocity)
This means, heavier object have bigger momentum compared to lighter or smaller object considering if they are moving at the same velocity.
Example:
Two objects with different mass running at the same velocity 20 m/s east and heavy object has 50 kg mass and lighter object has 25 kg mass. Which has greater momentum?
Heavy object Lighter Object
m (mass) 50 kg 25 kg
v (velocity) 20 m/s 20 m/s
p (momentum) ? ?
Momentum (heavy object) Momentum (Light Object)
p = mv p = mv
= 100 kg × 10 m/s = 50 kg × 10 m/s
= 1000 kg.m/s = 500 kg.m/s
Greater momentum Lesser momentum
Bigger object are usually heavy, which have greater momentum compared to smaller object that are lighter
