Explain. Balloon B has the greatest impulse. Impulse is equal to momentum change.

During a collision, an object always encounters an impulse and a change in momentum. During a collision, the impulse which an object experiences is equal to its velocity change. The velocity change of two respective objects involved in a collision will always be equal.

Impulse is force multiplied by time, and time of contact is the same for both, so the impulse is the same in magnitude for the two trucks. Change in momentum is equal to impulse, so changes in momenta are equal.

Impulse-Momentum Theorem: When a net. force acts on an object, the impulse of the net. force is equal to the change in momentum of. the object: F ∆t = m−→

2. Air bags in cars are designed with impulse, or momentum change principles. When a driver gets into an accident their momentum carries them forward into the steering wheel. By putting an airbag in the car, a smaller force is exerted over a longer period of time to change the momentum of the driver to a stop.

Summary

1. The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. J = ∆p.
2. If mass is constant, then… F∆t = m∆v.
3. If mass is changing, then… F dt = m dv + v dm.
4. The impulse-momentum theorem is logically equivalent to Newton’s second law of motion (the force law).

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

This change in momentum is called impulse, and it describes the quantity that we just saw: the force times the time interval it acts over. The greater the impulse, the greater the change in momentum.

The rate in change of momentum of a body is equal to the product of mass of an object and acceleartion produced in it due to the force acting on the body provided that the mass of the object remains constant. It is given as: Rate of change of momentum = mass × acceleration.

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force. The resultant force is equal to the rate of change of momentum.

Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt). And the change in momentum (ΔP) is also equal to the impulse (J).

The major relation would be that force results in a change in momentum. According to the second law of motion, the change of momentum of an object also called force which is given by mass times acceleration. The longer a force is applied, the larger the momentum is.

Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the rate of change of momentum.

Momentum is a vector quantity, given by the product of an object’s mass and velocity. If the velocity of the object is negative, i.e. the object is traveling in what has been chosen as the negative direction, the momentum will also be negative.

Explanation: Momentum is a vector quantity, given by the product of an object’s mass and velocity. If the velocity of the object is negative, i.e. the object is traveling in what has been chosen as the negative direction, the momentum will also be negative. →p=m⋅→v.

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.

Momentum is a vector. That means that momentum is a quantity that has a magnitude (or size) and a direction. The above problem is a one dimensional problem, so the object is moving along a straight line. In situations like this the momentum is usually stated to be positive to the right, and negative to the left.

The vertical component of the momentum is not conserved, because the net vertical force Fy–net is not zero. In the vertical direction, the space probe-Earth system needs to be considered and we find that the total momentum is conserved.
