## 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.
