What was the number we used as gravity?
What are some safety features in cars?
1.Seatbelt
2.Head-rest
3. Brakes
4.Airbags
What is another name for Newton's 1st law?
The Law of Inertia
How is Newton's 2nd law expressed?
F=ma
Define Force
A push or a pull
What was the drop height of the egg?
5.54 meters
What was the purpose of the seatbeat?
To stop the play-doe ball from getting yeeted
Define inertia
The tendency of an object to resist a change in motion
What two variables is acceleration dependent on?
Force and mass
Define net force
The sum of all the forces acting on an object
What was the average mass of an egg?
0.06 kg
Why have safety measures been put into cars?
To keep the driver, the passenger, and the other drivers safe when wreaks happen
Does every object have the same amount of inertia?
No, because inertia is related to mass.
What would happen to the speed of an object if it had more mass?
It would slow down
Define friction
It's the force that opposes the sliding motion of two surfaces that are touching each other
What was the equation used to find the average force being exerted?
Force=mass x acceleration
Will you have a greater impact force if you are going faster?
Yes, because as Newton's 3rd law states "For every action, there is an equal and opposite reaction."
How does size affect an object's inertia?
If an object is larger, it has more tendency to resist change in motion. And if an object is smaller it has less tendency resist change in motion
If an object is not accelerating, what can you determine about the sum of all the forces on the object?
Define air resistance
A friction like force that opposes the motion of objects that move through the air
What was the purpose of the egg drop?
What does Newton's 3rd law state?
For every action, there is an equal and opposite reaction
What does Newton's 1st law state?
An object in motion will stay in motion unless acted upon by an outside force. And an object at rest will stay at rest until acted upon by an outside force.
What does Newton's 2nd law state?
An object's acceleration is in the same direction as the net force on the object and is equal to the net force divided by it's mass
Define a balanced and an unbalanced force
1. Equal forces acting against each other-no acceleration
2. Unequal forces acting against each other- acceleration
