Be careful with this one. From how you posted the question, the most relative difference is ....The spelling of the words. They have different order of letters, they don't use all of the same letters, they sound different when spoken, and have different amount of letters. One word is longer than the other.

Where does kinetic energy go after it is used?
If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.
What is one way in which Ptolemy and Copernicus were similar n what is one way in which they were different?
asdasd
What is one way that atoms of different elements are different and one way that they are alike?
they are alike because they all have mass ther diffrent because there lines, and isotpes
Which way will you move if you have a 30 N pushing on you from the left and 10 N force pushing you on you from the right How much force will you be moving with?
The net force is 20 N push on you from the left. If there are no other forces on you, then you'll accelerate toward the right, just as if there were only one force of 20 N from the left on you. Your acceleration will be 20/your mass meters per second2. Your speed, velocity, momentum, and kinetic energy will all grow continuously.
How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
Can a body have kinetic energy without having momentum?
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
How is kinetic energy and momentum similar?
Answer #1:Kinetic energy is the energy possessed by an object due to its movementor motion. Momentum on the other hand, is the quantity of motion of anobject that is a product of its mass and velocity.====================================Answer #2:Kinetic Energy = 1/2 M V2kg-m2/s2 (Newton-meter = Joule)Momentum = M V kg-m/s (Newton-second)Numerical Difference = (1/2 M V2) - (M V) = (M V) x (1/2V -1) .
Why do you need momentum?
Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum
If kinetic energies of the two objects are equal is momentum also always equal?
Yes, and shame on your physics professor for not making this clear to you. Much of physics (some would say most) is about mathematics, so the clearest way for me to explain this is in mathematical terms. Where K is kinetic energy, m is mass, and v is velocity: K = (1/2)*m*(v*v) By (v*v), I mean velocity squared. Momentum, P, is the first derivative of kinetic energy with respect to velocity: P = dK/dv = m*v So momentum and kinetic energy are intimately linked. Same K, same P. K?
Why did one barbell have potential energy while the other did not?
it was anger
Why do rockets actually fly?
Conservation of momentum: The net momentum of the entire system (rocket plus propellant) is zero, so one is positive (this way) and one is negative (that way). If this way is up, then that way is down, or left and right, east and west, whatever way you want to look at it.
When does a planet have the greatest angular momentum?
A planet's angular momentum is constant, which is one way of stating Kepler's second law of planetary motion, the one about sweeping out equal areas. The angular momentum of the daily rotation is also constant.
A moving object must have potential energy?
An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must have momentum, velocity, and speed because if an object is in motion (has kinetic energy) it must be either gaining, losing, or at a constant momentum, it must have a velocity (basically speed) and speed because when an object is in motion, it MUST have a certain velocity or speed.
Can a single object have kinetic energy but zero momentum?
Yes. Kinetic energy is a scalar (non-directional) and momentum is a vector. That means if you have two or more objects in motion their kinetic energies always add. But their momentums must be combined using vector addition and you might get zero. The simple case is two identical masses moving with equal but opposite velocities. Their total momentum is zero because their directions of motion are opposite. --- Yes, Take two objects of the same mass, A and B, whose velocities, VA and vb, are opposite Ke = .5(m)(VA)^2 + .5(m)(vb)^2 = Plug in some numbers, m = 1 kg, VA = 10 m/s, vb = -10 m/s .5(1)(10)^2 + .5(1)(-10)^2 = 50 + 50 = 100 -- a positive number momentum can be found using p = mva + mvb so p = (1)(10) + (1)(-10) = 10 + -10 = 0
Why momentum is the product of mass and velocity?
It's defined that way.
How do collision exemplify the law of conservation of momentum?
The vector sum of momenta before and after the collision is the same. One way to visualize this is that if one of the colliding objects changes its momentum (mass x velocity) in one direction, then the other colliding object must needs change its momentum in the opposite direction - by the same amount, except for the direction.
