How can you find the value of the impulse?
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How do you find velocity when given the time and mass?
You can't. The mass is irrelevant to velocity. You need the distance.
How can you find force when mass and velocity are given?
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
How do you find acceleration when given only mass and velocity?
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
How can you find the value of the impulse?
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.
what is the relation of mass and velocity to impulse?
Impulse is equal to the change in momentum of an object, which is the product of its mass and velocity. So, the greater the mass or velocity of an object, the greater the impulse required to change its momentum.
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How to find potential energy when only mass and velocity time is given?
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.
How do you find velocity when given the time and mass?
You can't. The mass is irrelevant to velocity. You need the distance.
How can you find force when mass and velocity are given?
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
How do you find acceleration when given only mass and velocity?
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
A ball with a mass M is falling on to the ground with some velocity V1 and raising with velocity V2 find the impulse?
Impulse = |change in momentum| Initial momentum = MV1 down Final momentum = MV2 up Missing momentum = impulse = M ( V1 - V2 )
How do you find the mass if you have the momentum?
You can find the mass by dividing the momentum by the velocity. The formula for momentum is mass multiplied by velocity, so by rearranging the formula you can solve for mass by dividing momentum by velocity.
Is impulse delivered to an object equal to a change in the objects velocity?
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
