What is the difference between positive and negative momentum?
The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.
When ever an object is standing still the momentum is?
When an object is still it has no momentum. That is, the momentum is zero.
What are some true statements about momentum?
Momentum can be transferred from one object to another. Momentum can be slowed by an intervening object. Momentum can be hastened by an intervening object.
How do you find the total momentum of 2 objects moving at the same speed in opposite directions?
(1) Decide on a direction that you will consider positive. (2) Calculate the momentum of the object that travels in the "positive" direction. (3) Calculate the momentum of the object that travels in the "negative" direction (the momentum should be negative). (4) Add both numbers algebraically.
The momentum of a falling leaf is and the momentum of a falling pincone is what?
momentum is equal to the mass of an object x velocity of an object

The product of an object mass and velocity is called its What?
That's the object's linear momentum.
The momentum of a falling leaf is and the momentum of a falling pincone is what?
momentum is equal to the mass of an object x velocity of an object
What is the product of an object and the object's mass and velocity?
That's the object's linear momentum.
The product of an object's mass and velocity?
The product of an object's mass and velocity is called it's momentum. It is mostly called it's linear momentum to differentiate from the term angular momentum.
Is it true that an object never loses its momentum?
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.
Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
Why an object will move if its velocity is constant?
Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
What moving object depends on the objects mass and velocity?
That's the object's linear momentum.
