Define an Elastic collision

What is an event when two objects completely bounce off one another. Momentum is conserved.

200
Momentum is defined as this.
What is the product of mass and velocity, or in other words, inertia in motion.
200
The units for Impulse are these.
What is N*s
200
What two ways can an impulse change an objects momentum?
What is magnitude or direction.

This is the main difference between elastic and inelastic collisions.

What is elastic bounces apart and inelastic sticks together.

A deer with mass of 146 kg is running head-on toward you with a speed of 17m/s. You are going north. Find the momentum of the deer.
What is 2.5x10^3 kg*m/s south.

What impulse is exerted if a force of 25N acts on a car for 3.2s.

What is 80 N*s

300

Define Conservation of momentum in words, not an equation.

What is the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

Give me an Example of a Recoil Situation.
What is A bullet leaving a gun, a cannon and cannonball. etc.
400
A bullet traveling at 900m/s has a momentum of 4.5kg*m/s. The mass of this object is this.
What is .005kg
400
Which object has more impulse a bullet hitting a block with a force of 70N over .3s, or a hockey stick exerting 120N of force on a puck for .05s.
What is the bullet with a impulse of 21N*s
400

When a force exerted on an object, does a large force always produce a larger change in the objects momentum than a small force does? Explain.

What is no, because the change in momentum = F*t, it is possible for a large force applied over a very short time interval to change the momentum less than a smaller force applied over a longer time period.

RANDOM QUESTION: Newton's first law is also known as the law of what?

What is the law of inertia

500
Which object has more momentum? A 50 kg object moving at 10m/s or a 2.5 kg object moving at 200m/s
What is there momentum is equal.

All cars have air bags in the steering wheel and on the sides. What is the purpose of these air bags related to impulse.
What is to increase the time the person undergoes the impact.

RANDOM QUESTION: A 40 kg object on Earth has how much weight and how much mass?

Mass = 40 kg

Weight = 40*9.8 = 392 N

500

Why does a 500 kg car hitting a haystack and hitting  a brick wall result in the same change in momentum?

Momentum is a property of mass and velocity, and the car is going the same speed and has the same mass when it hits both objects. The difference is in the amount of force and the amount of time it takes while the car is interacting with the object.
