1. Let’s start with everyday language
What do you say when a sports team is on a roll?
They may not have the lead but they may have ___________
MOMENTUM
A team that has momentum is hard to stop.

2. Momentum

3. Newton’s First Law
A body in motion stays in motion…unless acted upon by an unbalanced force Momentum will only deal with inertia in motion

4. Which hurts more if he hits you?
Use the words mass and velocity

5. Momentum: p = mass x velocity
What is Momentum?
An object with a lot of momentum is also
hard to stop
Momentum: p = mass x velocity
Units: kg∙m/s
Momentum is also a vector (it has direction)

6. Something massive moving fast carries a lot of momentum
True or False? P=mv
Something massive moving fast carries a lot of momentum
True

7. True or False P=mv
Something REALLY massive moving slowly carries a lot of momentum.
True

8. True or False P= mv
True
Something with little mass doesn’t carry much momentum unless it goes fast

9. True or False P=mv
An object at rest has a very small amount of momentum
False, it has no momentum

10. Which has greater momentum? Bubble Wrecking Ball
Review
Which has greater momentum? Bubble Wrecking Ball

11. Let’s practice P=mv
A 1200 kg car drives west at 25 m/s. What is the car’s momentum?
Identify the variables:
1200 kg = mass
25m/s, west = velocity
P = mv = 1200 kg x 25 m/s = kg- m/s, west

12. A Project Get with your partner
Divide your paper into 8 squares (hotdog, hamburger, hamburger)
On the top put objects with a lot of momentum
On the bottom, their opposites

13. Large Mass Large Mass High Velocity High Velocity
Momentum
LARGE AMT OF MOMENTUM
Large Mass Large Mass High Velocity High Velocity
SMALL AMT OF MOMENTUM
Small Mass Small Mass Low Velocity Low Velocity
