We assume both masses are particles there is no wind resistance for the bullet and there is no friction between the motion surface and second point mass We further assume that the bullet is imbedded into the second mass at collision Under these cond ID: 8250 Download Pdf
of Momentum. Recall . Newton’s 3. rd. Law. : For every action force there is an equal and opposite reaction force.. Two colliding objects experience . equal. and . opposite. forces for the . same.
Introduction to Momentum. What is Momentum?. The quantity of motion of a moving body. Depends on mass and velocity. Measured by multiplying mass to the velocity. Vector. Measured in kg*m/s or N*s. How is momentum measured?.
Practice Problems. 1. Two grocery carts collide, a full one with a . mass . of 35 kg moving East at 2 m/s and an empty . one . with a . mass . of 10 kg moving West at 3 m/s. . After . the collision the full cart is moving .
The horizontal acceleration. The vertical acceleration. The horizontal component of the velocity. All of the above.. a. less than 0.5 s. . . b. more than 0.5 s.. c. 0.5 s.. A bullet is fired horizontally and hits the ground in 0.5 seconds. If it had been fired with twice the speed in the same direction, it would have hit the ground in ____. (Assume no air resistance.).
Momentum & Collisions. Momentum and Collisions. Momentum is a quantity of motion that depends on both the mass and velocity of the object in question:. Remember. : Momentum is a _______________ quantity, with the same sign as its velocity. As with any vector you can assign any direction as positive and the opposite as negative, but as convention we will refer to .
Lots of fun!. Win . valuable prizes!. 1.The reason padded dashboards are used in cars is that they . look nice and feel good. . decrease the impulse in a collision. . increase the force of impact in a collision. .
MOMENTUM Specification Forces and motion Forces, movement, shape and momentum know and use the relationship: momentum = mass × velocity p = m × v use the ideas of momentum to explain safety features
If a system has . no external forces . acting on it (. eg. no friction), then the system is . isolated.. Total momentum in an isolated system is said to be . conserved. . . A . system. is a pair or group of objects that are interacting in some way..

2 . Dimensions. 4.1 Newton's second law and momentum. Newton's second law states that the acceleration produced by a force on an object is directly proportional to the net force and inversely proportional to the mass of the object .
