Vocabulary
This is the pull or pull on an object.
What is force?
This is movement of an object.
What is motion?
This is what force is measured in.
What are Newtons?
True or False: More than one object can act on a force at a time.
What is true?
This is the tendency to resist change in motion.
What is inertia?
This is a force that opposes motion.
What is friction?
This is a force applied by a person or object onto another object.
What is applied force?
This is what the force of friction exerted by a surface depends on.
What is the smoothness of the surface?
This exerts gravity.
What are all objects with mass?
This is an object at rest will remain at rest unless acted on by unbalanced forces.
What is Newton's 1st law?
This is drag.
What are gases and liquids resist motion?
This is tension.
What is when two objects pull on a rope, string, wire or cable in opposite directions?
These are the 3 characteristics of force.
What are strength, direction and measured in Newtons?
This is the type of spring that would not exert spring force.
What is neutral?
This is Newton's 2nd law.
What is an object accelerates when a force acts on an object with mass?
This is net force.
What is the combined result of all forces acting on an object?
This is a balanced force.
What is when forces acting on an object are equal and balanced?
This is how you calculate net force.
What is the difference between the 2 forces?
These are non-contact forces.
What are gravity, electric force, and magnetic force?
This is Newton's 3rd law.
What is for every action there is an equal and opposite reaction?
This is momentum.
What is the quantity of motion an object has?
This is an unbalanced force.
What are when forces acting on an object not equal and balanced?
This is the relationship between the strength of Earth's gravity and the distance from Earth.
What is the force of gravity decreases when the distance between objects increases?
These are contact forces.
What are applied force, friction, spring force, tension, normal force, and buoyancy?
These are the patterns of motion and an example of each.
What are: sliding - soccer ball going in a straight line, rotation - ball spinning, revolution - earth around the sun, rolling - bowling ball rolling down a lane, and periodic - swing?
