what is linear momentum
Answers
Answer:
Linear Momentum
Momentum simply means mass in motion or it is the quantity of motion of a moving body. The more momentum a moving object has, the harder it is to stop. The quantitative value of momentum is equal to the product of mass ‘m’ of an object an its speed ‘v’. That is,
The momentum is a vector quantity, where the direction of the momentum will be as same as the direction of the velocity. Momentum is directly proportional to both velocity and mass. The linear momentum will always be conserved if there is no external force is present.
If the system consists of number of particles, the total momentum will be the sum of individual momentum of the individual particles. But to trigger the momentum an external impulse should be given to the particle rather than the internal one or the inverse relation of force and time says that the impulse is the change in momentum. The change in momentum
Δp = mΔv = Ft
Example:
When a baseball is thrown in a straight line through the air with a speed. When the ball is caught by hands, the momentum will have imparted to the hands and this will push the hand backwards. The more speed the ball has, the more the ball push the hands backward. This gives the importance of the velocity in momentum. But if two balls with different masses are thrown with same velocity, the ball with higher mass will push the hands back more than the lower mass ball do.
pls mark me as brianlist pls
Answer:
Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object's mass and also its velocity.
