Direction of momentum
WebThe change in momentum as the vehicle rebounds is greater than in an equivalent inelastic collision. The force on an occupant is therefore greater and that is clearly worse for the occupant. On the other hand, because it is an elastic collision no energy will be dissipated in deforming the vehicle. WebMomentum is mass times velocity. The symbol is p: p = m v Example: What is the momentum of a 1500 kg car going at highway speed of 28 m/s (about 100 km/h or 60 mph)? p = m v p = 1500 kg × 28 m/s p = 42,000 kg m/s The unit for momentum is: kg m/s (kilogram meter per second), or N s (Newton second) They are the same! 1 kg m/s = 1 N s

WebThe principle of momentum conservation, like energy conservation, is a direct consequence of Newton's laws of motion. Unlike energy, momentum is a vector so the direction must be taken into account. Conservation of momentum may be stated as the mathematical expression: This question hasn't been solved yet Ask an expert WebIn terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. What has the same direction as momentum? Momentum is a vector quantity. The direction of the momentum vector is the same as the direction of the velocity of the ball.
