Elastic vs. Inelastic

Do you know what elastic collision and Inelastic collision is? So if you don't know I will explain to you what each collision means and how both are different. 

Elastic collision- this collision is when two objects/people collide and they "bounce" off each other 😉

Inelastic collision- this collision is when two objects/people collide BUT "stick together" 🙄

Well if you don't understand with the definition I'll give you an example; 

                         EXAMPLES;

     Elastic collision: An example of this collision in my life is when I play with a bouncy ball. I would rewind the ball to the wall and the ball would "bounce" off the wall back to me. This is an example because the wall and the ball are colliding but the ball is bouncing off. 🏓👌🏼

Inelastic collision: An example of this collision in my life is when I was playin around with my bestie 👭 and I threw myself on her so I could pick her up and we stayed stuck together that I fell down with her on the floor. 😂😅 but she didn't get mad. In this example the part of me falling in the floor with her is the Inelastic collision because we collided and we stuck together that we BOTH fell down.😝

Now if you still don't understnd hea r pics

Elastic Collisions

What is momentum? Well, if u don't know what it is I can explain it to you. Momentum is the force times the speed of an object. And you can compare momentums between objects. 

- What has a greater momentum; a train at stationary or a moving skateboard...

    Of course, the moving skateboard has a greater momentum.  You must be asking " but why if the train weighs more than a skateboard?" Blah blah blah... Yes it's true a train weighs more but in this case when you want to find momentum you need the objects force (kg) times the objects speed (m). So, the train is at rest which isn't moving and the skateboard is moving. So, in this case the skateboard has the most momentum because it's moving a weight. And the train is at rest not moving at all which isn't doing work for train to move its weight. 😃👌🏼✏️

Work vs Power

The difference between work and power is that work is is the amount of force you do on an object so it can move at a certain distance. And power is the rate of how much work you put on an object. 

To find work you ONLY need force x distance. 

And to find the power you need work/ change of time.  

For work time doesn't matter BUT in power time DOES MATTER. 😄👌🏼✖️➗

Examples; 

Work done nd lots of power- An example of someone doing work with lots of power is a weight lifter picking up a 50 pound weight above his head with the time of 3s. And the second weightlifter is lifting the same weight but at the time of 10s. Which weightlifter has more power?

Well the second weight lifter because it's takin him more time to lift the same weight at the same distance. 

The one with less time is an expanse of little power because he's not taking all of his power to lift the weight up.
