Newton's first law
What is Inertia?
A resistance of an object to make it stop moving.
What is force?
A push or pull acting on the object.
What is Newton's third law?
When there is an action, there is an equal and opposite reaction.
What is velocity?
A way to measure the speed and direction of an object.
What is speed?
The rate at which an object moves through time.
What is Newton's first law also known as?
Law of inertia
What is force measured in?
Newtons
What does action equal?
reaction
What is the equation for velocity?
Velocity=distance/time
What is speed measured in?
Miles per hour
What is a good example of Newton's first law?
When a car stops suddenly, your body tries to keep moving forward at the car's previous speed due to inertia.
What is acceleration?
When an object moves and speeds up over time.
What is an example of Newton's third law?
When someone sits down on a chair.
What is velocity measured in?
meters per second
What is another way to measure speed?
Kilometers per hour
What does Mass and resistance mean?
Means that objects with greater mass have more inertia.
What is Mass?
The measure of how much matter there is.
Is this an example of Newton's third law? A car is going 60 mph, and it drives down a hill, and it's now going 80mph.
No
What would be an example of velocity?
55 meters per second
What would be an example of speed
60 kilometres per hour
What is the equation for net force?
Fnet=0
What is the equation for force?
F=M x A
True or False: A person doing push-ups is an example of Newton's third law.
Yes
What is another example of velocity?
10 meters per 1000 milliseconds
What would be another example of speed?
68 miles per hour
