The law of conservation of momentum states that momentum can neither be created nor destroyed; the total momentum of any closed system must remain the same. Momentum is mass times velocity. Thus‚ a ten pound object moving at 5 meters per second has the same momentum as a 2 pound object moving at 25 meters per second (for example). In order to alter the motion of one object‚ you have to transfer the momentum to another object. Now‚ this principle is not intuitively obvious‚ because we are constantly

What is momentum? Momentum of a body is defined as the mass multiplied by the velocity of this object. Momentum= m x v Momentum and Newton’s second law of motion: The resultant force is proportional to the change in momentum per a second. We know that force = mass x acceleration. So F (mv-mu)/t F m (v-u)/t = ma so F=kma Momentum is a vector quantity: Momentum has a direction as well as a magnitude Momentum and Newton’s first law of motion: An object remains at

Chapter 9 IMPULSE AND MOMENTUM COLLISION PROBLEMS A tennis ball and racket collision: a microscopic view COLLISION: FORCE VS TIME GRAPH A large force exerted during a small interval of time is called an impulsive force. LINEAR MOMENTUM The product of the particle’s mass and velocity is called the linear momentum p = mv As a vector quantity‚ the momentum can be represented in terms of its components: px= mvx py= mvy ALTERNATIVE FORM OF NEWTON’S SECOND LAW F = ma = m(dv/dt) =

Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate

Momentum‚ p‚ is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kg·m/s. During a collision objects transfer momentum to each other‚ resulting in different motions than before the collision. In this activity you will study

The initial velocity of the first cart as well as the masses of both carts was varied throughout multiple trials. Velcro placed on the ends of the carts caused the cars to stick together after colliding. Videos of the collision and the seconds
