## How do you solve impulses?

The object experiences an impulse equals the change of momentum. In equation form Ft=D v. Objects experience an impulse in collision; the impulse causes and equals the change of momentum.

**What is the impulse momentum theorem formula? **

Momentum and Impulse. The Impulse-Momentum Theory p=M v. The equation shows that momentum is directly proportional with the object’s mass and velocity (v). The greater the object’s velocity (v) or mass (m), the greater the momentum.

**What do you mean by impulse momentum theorem? **

Impulse-Momentum Theorem: When a net. Force acts on an object. The net’s impulse is the force. Force is equal to the change of momentum of. the object: Ft=m —

### What are 2 ways to increase impulse?

2 methods to increase the impulse are: 1) Increasing the force and 2) increasing the time that the force acts.

**Can you produce a net impulse on a car by sitting inside and pushing on the dashboard? **

Can a person create a net impulse in an automobile by pushing the buttons on the dashboard while sitting inside? You cannot cause a change in momentum by pushing on the dashboard. This is because external forces only produce changes in momentum. Railroad car A rolls at a given speed and collides with car B, which is the same mass.

**How does Dr Hewitt break the piece of wood? **

How is Dr. Hewitt capable of breaking a piece wood in his demonstration? His hand moves very quickly.

## Is it correct to say that if no net impulse is exerted on a system?

Is a statement correct that if a system has no net impulse, then there will be no change in its momentum? Yes, always. Yes, always. Momentum can be conserved in elastic or inelastic collisions. Railroad car A moves at a given speed and collides with car B of the exact same mass in an elastic collision.

**What has the greatest impulse? **

Explain. The greatest impulse is in Balloon B. Momentum change is equal to impulse.

**What impulse occurs when an average force of 10? **

Physics is the fourth

A | B |
---|---|

What impulse occurs when an average force of 10 N is exerted on a cart for 2.5 s? | 10 N x 2.5 s=25 Nxs |

What change in momentum did the cart undergo? | 25 kg x m/s |

If the mass of the cart is 2 kg and the cart is initially at rest, calculate it’s final speed. | 12.5 m/s |

### What do we call the quantity force distance?

a force sets an object into motion. The quantity impulse is the result of multiplying the force by its time of application. It changes the object’s momentum. What is the quantity force (x) distance? And what quantity can it change? work. object’s energy.

**What are the 2 main forms of mechanical energy? **

There are two types of mechanical energy. There are two main types of mechanical energy: motion energy and stored energy. Motion energy: This refers to the energy that something has when it moves (eg, a speeding cricket bat).

**What is force times distance? **

Work can be described as force multiplied by distance. The energy used to move an object by applying force is called work. Negative work can also be considered work.
