Does equal momentum mean equal kinetic energy?
No. Momentum is simply mass times velocity. But kinetic energy is one-half the mass times the square of the velocity, so it’s much more dependent on the velocity than on the mass.
What is the momentum if kinetic energy is zero?
If an object’s kinetic energy is zero then its momentum would also be zero. For an object to have no kinetic energy, it must not be moving.
Is kinetic energy equal to zero?
Since kinetic energy applies to moving objects, it is dependent on the object’s velocity. The equation for kinetic energy is KE=12mv2. Here, it is apparent that when v equals zero, the kinetic energy is also equal to zero. A force must act on the object in order to move it and cause work to be done.
How do you convert kinetic energy into momentum?
Relationship Between Kinetic Energy and Momentum. The relationship between kinetic energy and momentum is given by the equation T=p2/2m, where T is kinetic energy, p is momentum and m is mass. This relationship comes directly from the definitions of momentum (p=mv) and kinetic energy (T=½mv2).
What is the relation between kinetic energy and momentum formula?
Hence, the relation between the linear momentum and the kinetic energy is, p=√2m(K.
How are kinetic and momentum similar?
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 an object have 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.
Can momentum have no energy?
So, if the Kinetic energy is zero, momentum will be zero. Hence, a body cannot have momentum without having energy.
