When a force of 4 N acts on a mass of 2 kg for a time of 2s What is the rate of change of momentum?

A force of 4N imparts impulse of 4 per second. That is the rate of change of momentum: 4 per second. Since the force is acting on a mass of 2, the velocity will increase by 2 m/s every second.

What are two formulas for impulse?

Impulse Formula

• \vec{p} = refers to the momentum. m = refers to the mass of the object.
• Impulse = Force × (final time – initial time)
• I = refers to the impulse.
• Impulse = \Delta \vec{p} = \vec {p}_{final} – \vec{p}_{initial}
• \Delta \vec{p} = refers to the change in momentum.
• \Delta p = p_{f} – p_{i}
• \Delta p = p_{f} – p_{i}

What do you mean by term force?

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.

What is the acceleration of the object?

acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

What is impulse write its equation?

The formula for impulse is: Impulse = Force * time = force * Delta t. Delta t = t^final – t^initial. Because impulse is a measure of how much the momentum changes as a result of force acting on it for a period of time, an alternative formula for impulse is: Impulse = Delta p = p^final – p^initial.

What is impulse derive the formula for impulse?

Impulse can also be articulated as the rate of change of momentum. Where, Mass of the body is given as m. The velocity with which the body is moving is given as v….Impulse-momentum formula.

Impulse-momentum formula	J=Δp
When the mass is constant	FΔt=mΔv
When the mass is varying	Fdt=mdv+vdm
