Which of the Following Is/are the Unit of Momentum:

2 A very elastic rubber ball is dropped from a certain height and hits the floor with a downward speed v. 5 h When n 1 L π 0.

The Ultimate Conservation Of Momentum Worksheet Worksheets Conservation My Teacher

D N s.

. If an object has momentum then it must also have mechanical energy. More than 1 unit. The more massive object will have less momentum if its velocity is greater.

Which of the following is a correct unit for linear momentum. The two trucks move together at the same velocity after the collision. D The kinetic energy of the objects is zero joules after the collision.

Power dimension ML²T3 As length doubles power becomes 4 times. 5 h and π 0. As time and mass are constant and the length is doubled the momentum will be doubled.

SI Unit of Velocity Meter per Second ms. Momentum units MLT¹ so here mass and time are constant. The unit is not Newton it is Newton second Ns.

So Option B is correct. The Dimensions of Velocity are L T 1. SI Unit of Momentum Kg ms.

It is a vector quantity possessing a magnitude and a direction. N-s The change in momentum is equal to the impulse applied on an object. The momentum of B is the same after collision as it was.

Kgm²s² It is not the unit of momentum. A railway truck of mass 8000 kg travels along a level track at a velocity of 25 ms 1 and collides with a stationary truck of mass 12000 kg. Hence SI unit of momentum is the product of SI units of mass and Velocity.

E The vector sum of the velocities of the two objects is equal to zero ms after the collision. Here an object starts with 20 units kgms of momentum. The joule-second is a unit of action or of angular momentum.

When substituted into the Ns expression the result is the kg ms. Which of the following are units of momentum. It then encounters an impulse of 60 units Ns in the direction of motion.

J x sm E. It can be the unit of momentum. Joule - metre per second.

It can be the unit of momentum. The less massive object will have less momentum if the velocities are the same. If m is an objects mass and v is its velocity also a vector quantity then the objects momentum p is.

Kg x sm C. Momentum is the product of the mass of an object and the velocity it is moving with. In Newtonian mechanics linear momentum translational momentum or simply momentum is the product of the mass and velocity of an object.

This principle is attributable to which of the following scientists. So from this option A is false as impulse is not a force but changing momentum. A Aristotle B Einstein C Galileo D Newton 5.

The dimensional formula for momentum is. In the International System of Units SI the unit of measurement of. It cannot have vlaue 2 h The angular momentum of electron can have the values that are integral multiple of 2 π h L 2 π n h When n 3 L π 1.

B The total momentum of the objects is zero kgms after the collision. Since it is so elastic the ball bounces back with the same. Forcechange in momentumtime interval then change in momentum Force time interval.

C kg ms. So SI Unit of Momentum Kg ms. When comparing the momentum of two moving objects which of the following is correct.

Not enough information d. There could be more than one correct choice A N m. E kg m2s2.

SI Unit of Mass Kg. 5 h When n 5 L π 2. The object with the higher velocity will have less momentum if the masses are equal.

Kg x m2s2 Homework Equations. Mass is measured in kg and velocity in ms-1 therefore the SI unit of momentum will be kgms-1. The angular momentum of electron can have the values π 1.

If the mass is in grams and the velocity in centimetres per second then the unit of momentum will be gram-centimetres per second gcms. It is denoted by a symbol J or imp and expressed in a unit Ns. Which of the following are true about the relationship between momentum end energy.

4 Option 4. The dimensions of energy are ML2T - 2. 5 h π 2.

Hence the correct option is C momentum is doubled. B kg sm. The force direction differs.

What is the change. TRUE - The Ns is the unit of momentum. N x m B.

The dimensions of the Velocity are since the length is doubled there must be no change in time in the Velocity to make it double. Two smooth spheres A and B collide head on. Momentum is a form of energy.

A 60-unit impulse will change the momentum by 60 units either increasing or decreasing it. The joule-second symbol Js is the product of an SI derived unit the joule J and an SI base unit the second s. A piece of putty moving with 1 unit of momentum strikes and sticks to a heavy bowling ball that is initially at rest.

The dimensions of momentum are MLT - 1. The dimensions of the force are M L T 2. Power will become four times.

The momentum of A is the same after collision as it was before. It is given by the product of force and short duration of time. Less than 1 unit.

After the putty sticks to the ball both move with a combined momentum of Select one. 5 Option 5. Therefore the unit for momentum can be Newton.

So L is doubled. If we consider the situation when force is equivalent to the rate of change of momentum. As time and mass are constant and length is doubled the momentum will be doubled.

If the impulse is in the direction of an objects motion then it will increase the momentum. The Newton can be written as a kgms2.

The possible answers are. 1 Which of the following quantities are units of momentum. Kg x m2s D.

As impulse depends on the acted force when a collision arises from front behind or side the forces direction would be differed. The question is. Hence the correct options are c and d.

Which of the following statements isare true. C The objects stick together and move as one object after the collision.
