Calculate the momentum of an object if: a. its mass is 4kg and its velocity is 8m/s b. its mass is 500g and its velocity is 3m/s c. a force of 20N is applied to it for 6s and it moves from rest d. Calculate the momentum of a ball (mass...
The momentum of an object is calculated by multiplying its mass by its velocity. In a two-car collision, the total momentum before the collision is equal to the total momentum after the collision. 3. What happens to momentum in a two-car collision?
Impulse: Impulse (J) is the measure of the force delivered to an object during a time interval. Measured in Newton-seconds, impulse causes the momentum of an object to change. Force-time Graphs: When the amount of force applied to an object is graphed as a function of t...
An object's momentum is the product of its velocity and mass. The quantity describes, for instance, the impact that a moving vehicle has on an object that it hits or the penetrative power of a speeding bullet. When the object travels at a constant speed, it neither gains nor loses moment...
Working out the impact force when the object bounces afterward is a lot more difficult. The force is equal to the rate of change of momentum, so to do this you need to know the momentum of the object before and after the bounce. By calculating the change in momentum between the fall an...
Multiply the initial velocity of each object by its mass. Add these two products together to get the total momentum. For example, if both objects have a mass of 5 kilograms, one is at rest and the other is moving at 10 meters per second. The calculation would look like this: 5 x 10...

The mass of an oil tanker will be computed when we have the values of the momentum and speed of the tanker. The general relationships between these quantities are: P∝vP∝m Where P is the momentum, "m" is the mass, and v is the speed....
Can the kinetic energy of an object be negative in a collision? No, kinetic energy cannot be negative. It is always a positive value, as it is a measure of an object's motion and velocity.Similar threadsElastic Collision and Momentum of Ice Skaters Feb 15, 2021 Replies 16 Views ...
is the cyclical motion of an object around a fixed point. Many objects, such as the baseball in the above example, exhibit both types of movement at the same time; as a fly ball moves through the air from home plate toward the outfield fence, it also spins at a given rate around its...
