(a) Mass of elephant = 2000kg Velocity = 5 m/s Momentum = 2000 x 5 = 10000 kg.m/s (b) Mass of bullet = 0.02 kg Velocity = 400 m/s Mo...
Mass of the body, m = 25 kg Momentum p = 125 kg.m/s p = m x v v = = = 5 m/s Velocity of the body is 5 m/s.
Mass of car = 1500 kg Velocity v1 = 36 km/hr = 10 m/s Momentum p1 = 1500 x 10 = 15000 kg.m/s Velocity v2 = 72 km/hr = 20 m/s Momentum p2 =...
Mass of the toy car, m = 200 g = 0.2 kg Speed, v = 5 m/s Momentum, p = m x v = 0.2 x 5 = 1 kg.m/s
A karate player can break a pile of tiles with a single blow because he strikes the pile with his hand very fast. In doing so, the large momentum of h...
p = m x v This equation signifies that momentum of a body is the product of its mass and its velocity. Here, p is momentum of the body. m is t...
Since the speed of tennis ball and cricket ball is same, the momentum of cricket ball will be higher due to its mass being greater than mass of tennis...
(a) Mass (b) forward (c) backward (d) inertia (e) friction; air
The speed of the running bull should be multiplied with its mass to get its momentum.
Force is a vector quantity.
Isaac Newton gave the laws of motion.
Object B has more inertia. Since mass is a measure of inertia of a body and object B has greater mass, so it will have greater inertia.
Newton’s first law of motion is also known as Galileo’s law of inertia.
Inertia is the property of bodies to resist a change in their state of rest or motion.
Force of gravity causes this change in speed.
