  • Coefficient of friction, momentum, speed and distance

    This is because gravity on a still object causes the object to push down onto the surface where it rests, and there is an equal and opposite force - the normal force from the surface.

  • Newton's laws of motion: Collision

    But a reaction force will be applied on the second object by the first and it will get accelerated and hence can not remain at rest. The force acting on the two objects are action and reaction forces and are internal forces of the system.

  • Change in momentum and average force

    If the bat was in contact with the ball for .01 seconds, find the magnitude and direction of an average force the bat exerted. B). Find the magnitude of the impulse acting on the ball. C. Find the change in the balls momentum.

  • Gravitation: Potential energy and closest approach of star.

    momentum of an object is the moment of momentum and can be given by m*v*r the angular momentum of the object using equation (1) is given by Hence the angular momentum of the object is in terms of mass m and the constant h only.

  • Practice problems - Rolling, Torque , and Angular Momentum

    Find (a) the acceleration of the object, (b) the angular momentum of the object about the origin , (c) the torque about the origin acting on the object , and (d) the angle between the velocity of the object and the force acting on the object. 6.

  • Total time and the average force during the movement of a mass

    This law applies when a net force Fnet is applied, for a time interval t, to an object whose mass is M.

  • Mechanics force, mass and momentum of an object

    9577 Mechanics force, mass and momentum of an object Q. An object sitting on a smooth surface is given an impulse (force) to start from rest and reached a veloctiy of 5m/sec in 2 seconds. 1.

  • Newton's Laws

    also states that the rate of change of momentum of a body is equal to the force applied on it.

  • Car crashes into a barrier, impulse needed to stop the child

    = mass x initial speed = 19 x 8 = 152 kg m/s Impulse needed to stop the child is 152 kg.m/s b) Average force on the child = Rate of change of momentum = Change in momentum/Time = 152/0.05 = 3040 N c) Mass of an object with weight 3040 N = 3040
