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.
The direction of kinetic friction is always?
against motion For example, if I push a box to the left, kinetic friction is going to the left.
What is the momentum of an object going 22 ms and is 3 kg?
The momentum of the object is calculated by multiplying its mass by its velocity. So, for an object with a mass of 3 kg moving at a velocity of 22 m/s, the momentum would be 66 kg*m/s.
What is the momentum of a 25kg object going 4ms?
The momentum of the object can be calculated using the formula p = m * v, where p is the momentum, m is the mass, and v is the velocity. Plugging in the values gives: p = 25 kg * 4 m/s = 100 kgm/s. Therefore, the momentum of the 25kg object going at 4 m/s is 100 kgm/s.
Why does your body go left when a bus turns right?
Momentum. Momentum is mass x velocity. Velocity is speed in a direction. Even if the bus changes direction, you still have momentum in the original direction until some force pushes you in another direction. That takes a moment in a car or bus, so until your momentum is that of the bus, you'll still be going in a slightly different direction, which happens to seem 'outwards'.
When you throw an object on another object it breaks the first one why?
Momentum and the fact that one object is sitting on something that prevents it from moving or 'bouncing' away from the force. It isn't always going to happen that way, though most of the time it would be true.
How fast an object is going in a given direction?
An object's speed in a given direction is its velocity. Velocity is a vector quantity that includes both speed and direction. It describes how fast and in which direction an object is moving.
What is the velocity of an object is?
How fast it is going in a certain direction
What happens when two moving objects collide but one is going faster than the other?
When two moving objects collide and one is moving faster than the other, the faster object will transfer some of its momentum to the slower object upon impact. This transfer of momentum will cause both objects to change their speed and direction, depending on their masses and initial velocities. The extent of the change in motion will be determined by the conservation of momentum principle.
When a force changes direction an object is going is what energy?
aerodynamics
What is an object describes the speed and direction in which it is going?
Velocity is the term that describes the speed and direction in which an object is moving. It is a vector quantity that includes both magnitude (speed) and direction.
A 90 pound object going 30 miles per hour has how much force?
no force, it has momentum
