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
What is a force?
A push or a pull.
What is the formula for speed?
distance รท time
My mass would change if I went to a different planet. True or False
False
Newton's Second Law formula
Force = Mass x Acceleration
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 miles in 2 hours, what was my speed?
50 mi/hour
An object with a greater density than water will __________ when placed in water.
Sink
Every action has an equal and opposite reaction.
Newton's Third Law
Attraction between all matter. A force that pulls objects towards the ground.
Gravity
The sum of all forces acting on an object.
Net force.
If I am slowing down in the car, is that acceleration?
YES
Upward force that fluids exert on all matter.
buoyant force
Wearing seat belts to protect passengers when a car stops quickly is an example of which law?
Newton's First Law
The rate at which velocity (direction or speed) changes over time
Acceleration
Magnetism and gravity are examples of this type of force.
Distance force
Turning a corner is an example of acceleration. True or False
True

smaller
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.
The tendency of an object to resist a change in motion.
Inertia
When forces are _______________, there will be a change in motion.
unbalanced
What are the three ways to accelerate?
Speed up, Slow down, change direction
What is the formula for pressure?
pressure = force/area
