Newton's Laws
An object in motion stays in motion and an object at rest stays at rest unless acted upon by an outside force.
Newton's First Law
How fast an object is traveling
Speed
A push or a pull
Force
What is the formula for speed?
distance รท time
This would stay the same if I go to any other planet
Mass
Force = Mass x Acceleration is which law?
Newton's Second Law
Speed of an object in a certain direction
Velocity
If an equal force acts on a pencil and a text books, which one will have GREATER acceleration?
Pencil
If I traveled 100 kilometers in 2 hours, what was my speed?
50 km/hour
This would change if I go to another planet
weight
When two objects hit each other
Collision
This force is measured when we determine weight
Gravity
If I am slowing down in the car, is that acceleration?
YES
Is it easier to stop a moving object that has MORE mass or LESS mass?
It's easier to stop a moving object with LESS mass.
The rate at which velocity (direction or speed) changes over time
Acceleration
Force that does not cause motion.
Balanced force
Turning a corner is an example of acceleration. True or False
True
If two objects crash and one object exerts a force of 400 N left, how much force and in which direction will the other object exert force?
400 N right
If I am sitting in my chair, gravity pulls down on me. What is the opposite and equal force in this scenario?
The chair pushing UP on me.
What type of force slows down a skateboarder when he/she puts his/her foot down to brake?
Friction
Acceleration is the rate at which inertia changes over time. True or False?
FALSE - Acceleration is the rate at which VELOCITY changes over time.
Everything in the universe is in _____________.
