Newton's Laws
Name of Newton's First Law
What is the law of inertia?
This is a push or pull.
What is a force?
Determine the force needed to accelerate a 66kg skier at 2 m/s2
What is 132N?
A car is easier to push than a bus. This is an example of which of Newton's Laws?
What is Newton's Second Law?
This force requires objects to touch each other
What is contact force?
The equation that represents Newton's Second Law
What is F=ma?
This is a force of resistance between 2 objects
What is friction?
If an object has a net force of zero, this will happen to its motion
What is it will not change/nothing
You let the air out of a balloon- the air goes one way and the balloon goes the opposite direction. This is an example of which law of motion?
What is Newton's Third Law?
A force that resists motion
What is friction?
Name of Newton's Third Law
What is the law of action-reaction?
These are pushes and pulls that are done directly to an object.
What are applied forces?
When calculating net force we calculate these forces first
What is vertical forces? (Fg and FN)
The slingshot was pulled back and the rock propelled forward. This is an example of which law of motion?
What is Newton's Third Law?
The force that opposes gravity
What is normal force?
Name of Newton's Second Law
What is the law of acceleration?
These are forces that are exerted on an object that oppose gravity.
What are normal forces?
A student pushes on a crate with a force of 100N directed to the right. Determine the force the crate exerts on the student
What is 100 N to the left?
You left your book on a desk in Coach Sparks room and it is still there the next morning. This is an example of which law of motion?
What is Newton's First Law?
The main two non-contact forces we learned about
What is gravity (gravitational) and magnetic (magnetism)?
Newton's 3rd law states this, "For ...
What is every action there is an opposite and equal reaction?
These are two forces that are acting on an object that are equal in magnitude and opposite in direction.
What are balanced forces?
If a 60kg person on a 15kg sled is pushed with a force of 300 N, determine the person's acceleration
What is 4 m/s2?
The baseball went farther than the basketball when your classmate hit them with an aluminum bat. This is an example of which law of motion?
What is Newton's Second Law?
The order in which we usually draw force diagrams (1-4)
What is gravity, normal force, applied force, then frictional force?
