What is the force acting on a body having constant linear momentum?

Force, F = dp /dt ( rate of change of momentum). Therefore, only when the momentum is constant, will the acting force be Zero.

How much force is required to change the momentum of a body by 30 kg MS in 12 seconds?

F = mv-mu/t. here we can also write ∆P instead of mv-mu. Therefore, the force required to change the momentum of the body is 2. 5 Newton .

What is the formula for change in linear momentum?

As noted above, when mass is constant, the change in momentum is given by Δ p = mΔv = m ( v f − v i ) .

When no forces are acting on a body its momentum?

Answer: if the force acting on the body is zero. Force F=dp/dt ( rate of change of momentum). therefore only when the momentum is constant.

When balanced forces act on a body the body?

When balanced forces act on a body, the body remains in its state of rest or of uniform motion along a straight line.

What is the force required to change momentum?

Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.

How is force related to momentum of a body?

Force and momentum are directly proportional. Hence, momentum of the body increases with increase in the applied force. This relation is derived from Newton’s second law of motion. Thus rate of change of momentum and the force applied are directly proportional to each other.

How can force acting on a body be measured?

In the SI system, the magnitude of a force is measured in units called newtons, and in pounds in the British/American system. If a body is in motion, the energy of that motion can be quantified as the momentum of the object, the product of its mass and its velocity.
