Use the symbols 'm' for the object's mass, and 'v' for its velocity. Momentum is defined as 'mv' = the product of the object's mass and velocity. If the velocity doubles, then the new momentum is 'm' times '2v' = 2mv = 2 times (mv). This is just double the original momentum. So you can see that the magnitude of momentum is directly proportional to the magnitude of velocity, provided the mass remains constant.

What will happen to the momentum of a body whose velocity is doubled?
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
When velocity of body is doubled?
momentum is doubled, kinetic energy is quadrupled
When the mass of a moving object is doubled and its speed remains the same its momentum?
If the mass is doubled,speed should be halved to conserve momentum.
When a speed is doubled does its momentum double?
Yes
What depend on objects mass and velocity?
a moving objects momentum
What will happen to the momentum of a body whose velocity is doubled?
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
When kinetic energy doubled what happens to momentum?
Momentum increases
When velocity of body is doubled?
momentum is doubled, kinetic energy is quadrupled
When the mass of a moving object is doubled and its speed remains the same its momentum?
If the mass is doubled,speed should be halved to conserve momentum.
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
When a speed is doubled does its momentum double?
Yes
What depend on objects mass and velocity?
a moving objects momentum
If the velocity of an object is doubled the momentum is multiplied by?
4
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
How does kinetic energy change when the momentum is doubled?
energy is quadrupled
If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?
It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v
What would be the momentum of a passenger bus if its velocity were doubled?
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
