A collision

A car  has a mass 1000 kg and a speed of 10m/s and is heading east down a road.   A truck has a mass of 3000 kg and a speed of 10m/s head west on a road. 

Which vehicle has the greatest kinetic energy? 

Which vehicle has the most momentum? 

What happens to the momentum and kinetic energy if the cars collide?

Trains collide

Cameron is conducting a train going east at 36 meters per second with a mass of 6200kg.  Chris is conducting a train going west 55 meters per second and a mass of 3000 kg. Answer the following questions. 

1.  What is the momentum of the trains before they collide? 

2.  What is the momentum of the trains at the time of collision? 

3. What can be predict will happen to Cameron's train when it collides with Chris' train. 

Bumper Cars.

 A class takes a trip to an amusement park, the science teacher has the students ride on the bumper cars. How would riding the bumper cars help to demonstrate the law of conservation of momentum? 

Law of Conservation of Momentum.

 The law of conservation of momentum, tells us that when objects collide momentum is not lost , it is transferred.  If you designed an investigation with the collision between two objects,  could you predict the outcome of the collision? Explain. 

Conservation of Momentum

 The conservation of momentum helps us predict what will happen when two objects collide.  What happens when two objects that have the same momentum have a head on collision? 

Inertia and momentum

 How does mass affect the momentum and inertia of an object? 

momentum

 What is the formula to find momentum? 

                       

Acceleration

 What are the three ways an object can accelerate?

Ferrari Acceleration

 This Ferrari goes from 0 to 60 mph in 2.1 seconds.   

What would it mean if this car took 1.9 seconds to reach 60 mph? 

What would it mean if it took 2.6 seconds to reach 60 mph? 

What do people mean when they say a car does not have very good acceleration? 

What does this mean?

Last Day of Javelina week 2021

 There are three conditions need for natural selection to occur. The three conditions are variation,fitness, and inheritability. Differences must be present, those differences must help the species survive, and the differences can be passed onto offspring. Look at the picture below what is the evidence for natural selection? 

How fit is your Javelina?

 One of the three conditions that must be met for natural selection is a difference in fitness. The different traits must help the individual organism survive and reproduce. How did a different trait help the cactus survive and reproduce? What evidence is in the picture to show the cactus is reproducing?
