accelerating
What units are used to measure speed?
meters per second
If you were to throw a ball in space what would happen according to the Law of Inertia?
It will travel in a straight line indefinitely
What does "kg" stand for?
Kilograms.
If an object is has the force of 200 N and weighs 20 kg, what is the acceleration of the the object?

According to the experiment we did with the carts,
The higher the cart and the more weight in the cart the _____________ the cart goes.

What does " m/s2" stand for?
Meters per second squared
If no outside force is acting on an object, what will the object do?
Move with the same speed and direction.
If an object is moving at 30 m/s2 with the force of 10 N. What is the mass?

List 5 safety features in a modern car.
Crumple zones,
ABS
Seat belts
Airbags
Good tires
Sensors
What is this graph saying?
An object is moving at a constant rate.
explain crumple zones
Crumple zones slow down the car and allow for more time and less force to be acted upon the car and people.
what one is more stable? Explain in terms of center of mass
Because there center of mass is generally higher than other vehicles.
