Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Collision shopping experience:

1. Compare - without doubt the biggest advantage that the Collision offers shoppers today is the ability to compare thousands of Collision at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Collision? Wrong! If the Collision is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Collision then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Collision? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Collision and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Collision wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Collision then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Collision site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Collision, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Collision, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

In physics, collision means the action of bodies striking or coming together (tangenting). Dynamics happens when an object hits a plane surfaceCollisions involve forces (there is a change in velocity). Collisions can be elastic collision, meaning they conserve energy and momentum, inelastic collision, meaning they conserve momentum but not energy, or totally inelastic (or plastic), meaning they conserve momentum and the two objects stick together.

The magnitude of the velocity difference at impact is called the closing speed.

The field of Dynamics (mechanics) is concerned with moving and colliding objects.

Billiards In billiards, collisions play an important role. Because the collisions between billiard balls are nearly elastic, and the balls roll on a surface that produces low-rolling friction, their behaviour is often used to illustrate Newton's laws of motion.

Traffic In traffic such a collision can be between two vehicles, a vehicle and a person, a vehicle and an object (philosophy), two persons or a person and an object (and more if an animal is involved). It is an accident or even a disaster. At level crossings sometimes a train collides with a vehicle or person. Due to the velocity and mass of a train it needs a long distance to stop, typically longer than the train driving can see ahead. When a train collides with a car this is more likely to be deadly for the people in the car than for those in the train, because the train has more mass and momentum.
