Formulas & Units
This is the unit for force.
What is (N)?
This is the rate at which velocity changes.
What is acceleration?
This law describes that an object at rest will stay at rest until acted on by another force, otherwise known as the law of inertia.
What is Newton's 1st Law?
If a person is pushed to the left with 45 N of force, which direction will they go?
Ignore friction and imagine the person has no opposing force on them in any other direction.
They will go left with 45 N of force.
These are the four cardinal directions.
What are north, south, east, and west?
This is the formula for velocity.
What is displacement/time?
This is a quantity that has both magnitude and direction. (displacement, velocity etc.)
What is a vector quality?
This law talks about the relationship between force, mass, and acceleration.
What is Newton's 2nd Law?
What is the mass of the object?
F=60 N.
A=3 m/s2
The mass is 20 kg.
This is the resistance that one surface or object encounters when moving over another.
What is friction?
This is the formula for Newton's Second Law of Motion.
What is F=MA? (Force=mass x acceleration)
What is speed?
According to the 3rd law of motion, every action has an ____ and _______ reaction.
According to the 3rd law of motion, every action has an equal and opposite reaction.
If an object has 45 N right acting on it and 90 N left acting on it, where will the object go and with how many newtons?
The object will go left with 45 N.
What law of motion helps us (hint: and basketball players :) ) jump up?
Newton's 3rd Law of Motion
This is the unit for acceleration.
What is m/s/s or m/s2?
What is the difference between distance and displacement?
Distance is how much an object has traveled over a period of time. Displacement is the (shortest) distance and direction from the original location to the current location.
This law best explains inertia.
What is Newton's 1st Law?
If a box is standing still, yet 30 N of force is pushing it to the left, what amount of force is pushing it to the right?
30 N of force is pushing the box to the right. The forces balance out and the box stays still.
This is a measure of the force of gravity on an object.(mg)
What is weight?
This is the formula for acceleration.
What is s2-s1 divided by t?
This is the support force exerted upon an object that is in contact with another stable object.
What is normal force?
Which law best explains why it takes more force to move an object with greater mass the same distance as an object with less mass?
Newton's 2nd Law best explains this with the equation F=MA.
The 62 kg box would go farther. It takes more force to move an object with greater mass farther. The second law of motion explains this.
How do Newton's Laws of motion apply to everyday life?
