What would happen to change in momentum if force is doubled?

What would happen to change in momentum if force is doubled?

Momentum of a body of given mass, is directly proportiional to its velocity. In fact momentum is mass multiplied by velocity. Kinetic energy of a body of given mass, is directly proportiional to its square of its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled.

What would be the momentum of an object if it were moving at the speed of light?

At the speed of light, the object’s momentum would be infinite, so it would require an infinite impulse to get it there.

What is the momentum of a 40 kg freshman moving southward at 2 m s?

40-kg freshman moving southward at 2 m/s. p = m*v 540 kg•m/s, east, 80 kg•m/s, south, 20 000 kg•m/s, north, A car possesses 20 000 units of momentum.

What will be the percentage change in momentum of a body when both its mass and velocity are doubled?

Momentum of a body of given mass, is directly proportiional to its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units. and percentage increase in kinetic energy is 400−100=300% .

When mass is doubled then how is acceleration changes?

As mass is doubled, acceleration becomes half.

What is the momentum of a person at rest?

0
The momentum of any object that is at rest is 0. Objects at rest do not have momentum – they do not have any “mass in motion.” Both variables – mass and velocity – are important in comparing the momentum of two objects.

What would be the momentum of an object if it were moving at the speed of light quizlet?

What would be the momentum of an object if it were moving at the speed of light? The momentum would be infinite.

What is the momentum of a 60kg halfback moving eastward at 9 m s?

540kg⋅m/s
Thus, the momentum of the halfback in the east direction is 540kg⋅m/s 540 k g ⋅ m / s .

How will the momentum of body change if its kinetic energy is doubled?

Because momentum is directly proportional to the speed as well as mass, doubling the kinetic energy by changing the speed will increase the momentum by a factor , or make it times larger.

What is the percentage change in momentum?

The percentage increase in the momentum of the body is P′−PP×100=√2P−PP×100=(√2−1)×100=41.1%.

How many units of momentum does a car have?

A car possesses 20 000 units of momentum. What would be the car’s new momentum if a. its velocity was doubled. b. its velocity was tripled. d. both its velocity was doubled and its mass was doubled. Nice work!

How does the amount of momentum of an object depend on?

The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. Momentum = mass • velocity

How is momentum change related to the impulse?

Momentum change equals the impulse; if each cart has the same impulse, then it would follow that they have the same momentum change. Jennifer, who has a mass of 50.0 kg, is riding at 35.0 m/s in her red sports car when she must suddenly slam on the brakes to avoid hitting a deer crossing the road.

How is the mass of a cart related to its momentum?

The total mass of loaded cart is 1.0 kg and its momentum is 2.0 kg•m/s. If the cart was instead loaded with three 0.5-kg bricks, then the total mass of the loaded cart would be 2.0 kg and its momentum would be 4.0 kg•m/s. A doubling of the mass results in a doubling of the momentum.
