The two impulses are opposite in direction. = final momentum – initial momentum = 0.3 kg ms -1 – 0.3 kg ms -1 = – 0.05 x 6 kg ms -1 = – 0.3 kg ms -1 Impulse imparted to each ball due to the other Initial momentum of each ball before collisionįinal momentum of each ball after collision What is the impulse imparted to each ball due to the other? (2 marks)Īns. Two billiard balls, each of mass 0.05 kg, moving in opposite directions with speed 6 ms -1 collide and rebound with the same speed. What is the (a) force on the particle for t 4 s, 0 < t < 4 s? (b) impulse at t = 0 and t = 4 s? (Consider one-dimensional motion only). Figure shows the position-time graph of a particle of mass 4 kg. I = Δp is the formula of finding Impulse. What is the formula for finding Impulse? (2 marks)Īns. The second law states that the rate of change of momentum of an object is directly proportional to the force applied, or, for an object with constant mass, that the net force on an object is equal to the mass of that object multiplied by the acceleration. What is Newton's Second Law? (2 marks)Īns. The symbol of Impulse is I and its SI unit is N. What is the SI Unit of impulse? (2 marks)Īns. While playing Carroms, the striker hits the coin for a very short time then to returns back or falls in the pocket. Kickstarting a bike, when we kick for a small period while starting a bike is an example of impulse force The bat is in contact with the ball for very little time but changes its course quite significantly. A few examples -īatsman hitting the ball while playing cricket. Impulse is any force that for a very small amount of time. What are some daily life examples of impulse? (2 marks)Īns. Impulse of a force for a given time is equal to the total change in momentum of the body during the given time. If the force of an impulse is changing with time, then the impulse is measured by finding the area bound by the force-time graph for that force. The impulse of a force is a vector quantity and its SI unit is 1 Nm. Impulse is defined as the product of force and the small time interval for which it acts. Forces acting for short duration are called impulsive forces. What is Impulse in Physics? (2 marks)Īns.
