How does the momentum of two objects before a collision compare with the momentum after the collision?
conservation of momentum
What 2 things affect the gravitational force exerted by objects?
The two things that affect the gravitational force is Mass and Distance.
How could two objects travailing at the same speed have different amounts of momentum?
Momentum is a vector and so obeys the laws of vector addition. These imply that the momentum of two two objects will be the sum of the individual momentum only if the objects are moving in the same direction.
Is momentum conserved when two or more objects push away from each other?
Of course it is. Momentum is always conserved.
Do two objects that have the same mass and velocity always have the same momentum?
yes
How does the momentum of two objects before a collision compare with the momentum after the collision?
conservation of momentum
What two things affect falling objects?
gravity and mass
What 2 things affect the gravitational force exerted by objects?
The two things that affect the gravitational force is Mass and Distance.
When can the momentum of two objects be cancelled?
The momentum can be cancelled when the objects are equal and opposite in momentum, 0= p1 + p2, thus p1=- p2. Newton's 3rd law.
What never changes when two or more objects collide?
The total momentum of all the objects does not change when two or more objects collide together. An object that is smaller in mass can not have more momentum after the collusion.
When can the momentum of two moving objects be cancelled?
The momentum can be cancelled when the objects are equal and opposite in momentum, 0= p1 + p2, thus p1=- p2. Newton's 3rd law.
Does the total amount of momentum stay the same when two objects interact?
Yes. Momentum is conserved.
How could two objects travailing at the same speed have different amounts of momentum?
Momentum is a vector and so obeys the laws of vector addition. These imply that the momentum of two two objects will be the sum of the individual momentum only if the objects are moving in the same direction.
Is momentum conserved when two or more objects push away from each other?
Of course it is. Momentum is always conserved.
What would you find out when you add up two momentums?
The combined momentum of the two objects.
What two factor affect momentum?
force and acceleration
What are the two factors that affect an objects energy?
What are the two factors that affect an objects kinetic energy
