Can A Single Object Have A Kinetic Energy And No Momentum?

Can an object have zero momentum?

An object can have zero momentum when either its mass or its velocity is zero.

Since, negetive mass doesn’t exist, the velocity should be zero and thus, the object must be at rest..

Is momentum directly proportional to kinetic energy?

Ans. In a constant object, momentum increases directly with speed whereas kinetic energy increases the square of the velocity due to energy momentum relation.

Which car has the most kinetic energy?

Answer: The first car has the most kinetic energy.

Can you find kinetic energy without velocity?

You cannot. The term kinetic means there is movement. And therefore, you need to know something about the movement in order to determine kinetic energy. If the object is at a height and is not moving relative to it’s environment, then you can say that the Kinetic energy is zero.

What happens when two objects with the same momentum collide?

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.

Can an object have a kinetic energy but no momentum?

FALSE – If an object does NOT have momentum, then it definitely does NOT have kinetic energy. However, it could have some potential energy and thus have mechanical energy.

What is the momentum of an object zero?

An object can have zero momentum when either its mass or its velocity is zero. Since, negetive mass doesn’t exist, the velocity should be zero and thus, the object must be at rest.

Does momentum change with direction?

Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel. This means that the momentum of an object can change if: the object speeds up or slows down.

Which if either has greater momentum a 1 kg ball moving at 2 m/s or a 2 kg ball moving at 1 m s?

Which if either has a greater momentum: a 1-kg moving at 2m/s or a 2-kg bad moving at 1 m/s. Which has a greater kinetic energy? Same momentum, but different KE. The 1-kg ball traveling at 2 m/s has a greater KE.

Is momentum conserved when a ball bounces?

conservation of momentum: The amount of momentum in a system remains the same after a collision. elastic collision: A collision in which all of the momentum is conserved. For example, a ball that bounces back up to its original height. … momentum: Mass in motion.

Can a single object have a kinetic energy and no momentum B can a group of two or more objects have a total kinetic energy that is not zero but a total momentum that is zero?

Answer Expert Verified thus, the momentum cannot be zero if it has kinetic energy since kinetic energy is proportional to the square of velocity and momentum is proportional to the velocity. the two or more object is able to have kinetic energy but zero momentum. … but the total kinetic energy is not zero.

Can a system of two objects have nonzero total kinetic energy but zero total momentum?

Since kinetic energy is12mv2and momentum ismv, an object that has kinetic energy mustalso have momentum.It is possible, however, for a system of objects to have nonzero kineticenergy but zero momentum. … Since there is no change in momentum, there is also no impulse.

Can a lighter object have more momentum than a heavier one how?

Question: Can A Lighter Object Have More Momentum Than A Heavier One? … No, Because Momentum Is Independent Of The Mass Of The Object.

Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

What’s the difference between momentum and kinetic energy?

Some people think momentum and kinetic energy are the same. They are both related to an object’s velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object’s energy from motion, and is a scalar.

Can a tiny bullet have more momentum than a huge truck?

Momentum is not equal to the mass of an object divided by its velocity. The momentum of an object can change. Two objects with the same mass will always have the same momentum. … A tiny bullet can have more momentum than a huge truck.

Is momentum can be negative?

Momentum can be negative. Momentum is a vector quantity, meaning it has both magnitude and direction.
