Readers ask: How can a small force impart the same momentum to an object as a large force?

How does momentum relate to force?

Force is a measure of the change of momentum over time. It can be written as F = mass x change in velocity / time. In practical terms, the momentum of an object increases when a force is acting upon it, because the force is causing it to accelerate, and to have an increase in velocity.

Can a small force deliver a greater impulse than a large force?

6) Is it possible for a body to receive a larger impulse from a small force than from a large force? Answer: Yes. Impulse is force times time. A small force acting over a long time can easily provide more impulse (change in momentum) than a larger force which acts for a much shorter time.

How can a ball with a small mass have the same momentum as a ball with a large mass?

Same momentum means that the large mass must have a small velocity (so that their product is equal to the small mass times a large velocity). Since they have the same momentum, the object with the larger velocity has a larger kinetic energy – that’s the object with the small mass.

Is it possible to obtain a large impulse from a smaller force acting on an object?

Yes; impulse is the force applied multiplied by the time during which it is applied (J=FΔt J = F Δ t ), so if a small force acts for a long time, it may result in a larger impulse than a large force acting for a small time.

Which motion does not require force to maintain it?

Answer. The one type of motion that can be maintained in the absence of an interfering force is the uniform linear motion. Linear motion is a type of motion in which the object in motion moves along a straight line an is uni-dimensional.

Is force directly proportional to momentum?

Newton’s second law states that the rate of change of momentum of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force. A force acting on a system affects its momentum. If there is no net external force, there is no change in momentum.

Does impulse increase with time?

Momentum is mass in motion, and any moving object can have momentum. An object’s change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. As you decrease the time of the impulse, the force increases.

Can the impulse of a force be zero?

If the net If the net external impulse is zero, for example, impulse is zero, for example, if the net if the net external force is zero, force is zero, the net momentum of a system is conserved.

Why do gymnasts use thick floor mats?

Why do gymnasts use floor mats that are very thick? Because the cushion in the mat extends the time and lessens the force. the steel cord will stretch only a little, resulting in a short time of stop and a corresponding large force.

Can a tiny bullet have more momentum than a huge truck?

Momentum is not equal to the mass of an object divided by its velocity. The momentum of an object can change. Two objects with the same mass will always have the same momentum. A tiny bullet can have more momentum than a huge truck.

Is momentum conserved when a ball is dropped?

Linear momentum of a system remains conserved unless an external force acts on it. Since during free fall, a gravitational force acts on the body, it’s momentum will not remain conserved.

Can two different mass bodies have same kinetic energy Why?

Phillip E. Kinetic energy is a function of mass and velocity, so objects of different masses can have the same kinetic energy.

What is impulse equal to?

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.

Why can a batter hit a pitched baseball?

WHY can a batter hit a pitched baseball further than a ball tossed in the air by the batter? The bat changes the direction of the momentum (with little loss of velocity) and the batter swings at the ball adding more impulse to the ball. These motions combined allow for a home run.

How can I decrease the mass of the object?

All you need to do is it drop it. Then some of the object’s mass-energy, which we call potential energy, is converted into kinetic energy, which ends up getting dissipated. You’re then left with a mass deficit. The mass of the object is reduced.
