How is the momentum of an object determined answer?
Answer: Momentum can be calculated by multiplying the mass of an object by its forward velocity. ( mv = kg*m/s) Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally.
How do you find an object’s momentum?
The momentum of a moving object can be determined by multiplying the object’s mass by its velocity. Like velocity, acceleration, and force, momentum is described by both a direction and a strength. The momentum of an object is in the same direction as its velocity.
How is the momentum of an object determined for kids?
In physics, momentum of an object is equal to the mass times the velocity. where p is the momentum, m is the mass, and v is the velocity. From this equation you can see that both the velocity of the object and the mass have an equal impact on the amount of momentum.
Does momentum have a direction?
Momentum is a vector quantity; i.e., it has both magnitude and direction.
What is the formula for change in momentum?
1) The change in momentum of an object is its mass times the change in its velocity. Δp=m⋅(Δv)=m⋅(vf−vi) .
What is the momentum of a child?
The momentum of a body of mass m kg traveling at a velocity v m/s is equal to M =m*v kg*m/s. The total mass of the child and her wagon is 22 kg. Its velocity is 1.5 m/s. The momentum of the child and wagon is equal to 22*1.5 = 33 kg*m/s.
What happens when two objects with the same momentum collide?
When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.
What is momentum a measure of?
Momentum is a measure of inertia in motion. Momentum is equal to mass multiplied by velocity. the mass of the object or its velocity or both change.
What is momentum in one word answer?
Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving. An example of momentum is how quickly a car is moving down a hill. (physics) (of a body in motion) The product of its mass and velocity.
What are two ways to change momentum?
Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
What is the formula for change in momentum Class 9?
The change in momentum = m × (v – u). Here a = [(v – u)t (v – u) t ] is the acceleration, which is the rate of change of velocity. The quantity, k is a constant of proportionality.
What happens to energy when two objects collide?
When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced. Light also transfers energy from place to place.
