Speed plus direction.
What is velocity?
What is the equation for the 2nd law of motion?
Force = Mass x Acceleration
F = MA
A bat hits a ball with 1000 N of force. How much force does the ball push back on the bat?
1000 N
This is the state did Ms. Stypeck grow up in
Maryland

A force between an object and the surface it is moving over.
What is Friction?
What force is needed to make a 2 kg ball accelerate 10 m/s2
A 4 kg bowling ball collides with a 1 kg soccer ball. Which ball will experience a larger change in velocity?
Soccer ball.
Smaller mass. While the force exerted on each ball is the same, the ball with the smaller mass will experience more acceleration.
These are Ms. Stypeck's cat's names
Bert and Tibbs

Why is a bowling ball harder to stop than a soccer ball with the same velocity?
**must use language from the 1st law of motion!!
Bowling Ball has more INERTIA.
If a force of 80 N is applied to a 8 kg object what will be that object's acceleration?
10 m/s2
When objects collide, the force exerted on both object is __________ and __________.
EQUAL, OPPOSITE

This is the year that Ms. Stypeck was born.
What is 1994?
Calculate the TOTAL NET FORCES on the cart:

0 N
Name TWO out of the THREE different units for force, mass, and acceleration.
Force: Newtons (N)
Mass: Kilograms (kg)
Acceleration: Meters per seconds squared (m/s2)
When a film canister rocket launches, what force causes the rocket to move upwards?
When the film canister rocket pushes downward, an equal and opposite force pushes the rocket upward, making it launch into the air
This is the color of Ms. Stypeck's car.
What is Blue?
Name two forces acting on the inertia tower cups:

Gravity, friction from the cards against the cups, force from the hand pulling the cards, upward force of the table
A 5 kg block is pulled across a table by a horizontal force of 20 N with a frictional force of 10 N opposing the motion. What is it's acceleration?
2 m/s2
SPLAT: A fly hits the windshield of a car. The third law of motion says the force on the fly and the car is the same strength.
Why did the fly go SPLAT, but the car did not get damaged?
Fly had a MUCH smaller mass than the car.
The fly's mass could not withstand the change in velocity.
