Momentum is a vector and has the same direction as velocity v. Since mass is a scalar, when velocity is in a negative direction (i.e., opposite the direction of motion), the momentum will also be in a negative direction; and when velocity is in a positive direction, momentum will likewise be in a positive direction. The SI unit for momentum is ...
Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p . By definition, p = m ⋅ v. Where m is the mass and v is the velocity. The standard units for momentum are kg ⋅ m / s , and momentum is always a vector quantity.
- I as well am not really understanding what impulse is exactly.so.... if you want to change the momentum of an object, you have to apply a force. OK?? But if you apply that force for a long time then the moment...

Feb 20, 2022 · Impulse is the change in momentum vector. Therefore the x− x − component of impulse is equal to - 2mμ 2 m μ and the y− y − component of impulse is equal to zero. Now consider the change in momentum of the second ball. pxi = m/mucos30o; pyi = −mμ30o (8.2.5) (8.2.5) p x i = m / m u c o s 30 o; p y i = − m μ 30 o.

Choose the \ (y\) -axis to be along the wall in the plane of the second ball’s motion. The momentum direction and the velocity direction are the same. Solution for (a) The first ball bounces directly into the wall and exerts a force on it in the \ (+x\) direction. Therefore the wall exerts a force on the ball in the \ (-x\) direction.

Impulse is the area under a force vs. time graph. This graph can be analyzed as two separate areas to find the total impulse over time t 1 + t 2 . A 1 is a rectangle of height F 0 and width t 1 . A 2 is a triangle of height F 0 and base t 2 . The total impulse on the object over t 1 + t 2 is.
