Momentum Momentum = mass x velocity ( Kgm/s ) (kg) (m/s) If an object is moving towards you, your safety will depend on * how massive the object is * how.

Conservation of Momentum. Momentum  The velocity and mass of an object give it momentum.  The larger the velocity and mass, the larger the momentum.

Velocity and Momentum ► Write your own definition  Velocity  Momentum

Velocity ► What was your definition of velocity? ► Can we write it scientifically?

Velocity and Speed ► How are velocity and speed related? ► How do they differ?

Thinking time… ► Can two objects have the same speed, but different velocities? ► Examples?

Velocity- Linear ► What does velocity look like linearly? ► bug-motion-2d bug-motion-2d bug-motion-2d

Velocity on a Curve ► When happens to the velocity of an object as it goes around a curve? ► bug-motion-2d bug-motion-2d bug-motion-2d

Relative Motion ► Think about this…  Suppose you are riding on a train that is going 80 km/h. If you walk toward the front of the train at a speed of 1.2 km/h relative to the train, your velocity relative to the ground is 81.2 km/h in the direction the train is moving.

Relative Motion ► Think about this…  Suppose you are riding on a train that is going 80 km/h. If you walk toward the back of the train at a speed of 1.2 km/h relative to the train.  What is your velocity relative to the ground?

Momentum ► What was your definition of momentum? ► Can we write it scientifically?

Momentum ► How do we express momentum mathematically? ► Momentum = p ► Mass = m ► Velocity = v ► What are the units of momentum?

Example ► What is the momentum of a car with a mass of 1300 kg traveling north at a speed of 28 m/s? ► A baseball has a momentum of 6.0 kgm/s south and a mass of 0.15 kg. What is the baseball’s speed?

Your Turn ► Find the mass of a person walking west at a speed of 0.8 m/s with a momentum of 52.0 kgm/s west. ► The mass of a basketball is three times greater than that mass of a softball. Compare the momentums of a softball and a basketball if they both are moving at the same velocity.

Mini Lab- Video ► physics/linear-momentum/ physics/linear-momentum/ physics/linear-momentum/ ► Think about these as you watch:  How is the jumper able to jump so far?  Where does her momentum come from?  What happens to the momentum of the person who stays on the platform?  Why use the swing in the act?  Why use the swing in the act?  How is the jumper able to go so far?  How would this act change if different people were on the swing? What if the launcher was heavier? What would happen with a light launcher and a heavy jumper?  If the jumper’s momentum is increased in the launch, where is the corresponding decrease?  If the jumper’s momentum is increased in the launch, where is the corresponding decrease?  What happens when a heavy object collides with a light object?

Questions to Answer ► How is the jumper able to jump so far? ► Where does her momentum come from? ► What happens to the momentum of the person who stays on the platform? ► Why use the swing in the act? ► Why use the swing in the act? ► How is the jumper able to go so far? ► How would this act change if different people were on the swing? ► What if the launcher was heavier? What would happen with a light launcher and a heavy jumper? ► If the jumper’s momentum is increased in the launch, where is the corresponding decrease? ► If the jumper’s momentum is increased in the launch, where is the corresponding decrease? ► What happens when a heavy object collides with a light object?
