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?

 Please select one word from the list below. Write a sentence that defines or gives an example of the vocabulary word. 

Velocity

 A train is traveling from NewYork to Chicago. The length of the trip is 22 hours and 15 minutes. The Distance the train travels is 725 miles.  Please answer the following questions. 

A.  What is the average velocity of the train? 

B.   Would the train have a greater distance or displacement  at the end of the trip? 

C. What would the speed of the train be if the trip took 8  hours? 

Airplane Flight

 An airplane files a distance of 650km at an average speed of 300km /h. How long was the flight?
