Newton's 1st and 2nd Law
F= ma is the formula for this law.
What is Newton's 2nd Law
A force does this to an object.
A baseball hits this with an equal force?
What is a bat?
A push or a pull on an object with mass that causes it to change velocity (to accelerate).
What is a force?
Given the choices of grass, ice or wooden flooring, this surface has the least friction.
What is ice?
An object in motion will stay in motion, and an object at rest will remain at rest unless acted on by an outside, unbalanced force is an example of this law.
What is Newton's First Law?
What is the Action-Reaction Law?
A bowling ball will hit these with an equal force.
What are bowling pins?
Force that resists the sliding or rolling of one solid object over another.
What is friction?
Given the choices of carpet, tile or linoleum, this surface has the most friction.
What is carpet?
The Law of Inertia is also known as this law.
What is Newton's First Law?
An object with less resistance would be said to have very little of this.
What is friction?
When we push off the ground, the reaction force is this.
For every action is an equal and opposite reaction.
If a karate instructor chops a block of wood with his hand, then this reaction force pushes back to the instructor.
What is the block of wood?
If a person has more mass, then they will also have more of this.
What is inertia?
To generate more force you will need to generate more of this.
What is momentum?
When a bird flies, its wings push air in a downward and a backward direction. The reaction force would be this.
What is the air resistance pushes back on the bird in the opposite directions—upward and forward.
Change of position, either considered apart from, or as a characteristic of, something that moves.
What is motion?
This feature on a vehicle slows it down gradually and increases the stopping time.
What is the crumple zone?
This term is just a change in momentum.
What is impulse?
What is the Law of Conservation of Momentum?
We often don't feel these forces because of this reason.
What is the Earth has so much mass?
What is used for judging, evaluating, or selecting something.
What is criteria?
The size of the forces on the first object equals the size of the forces on the second object. The direction of the force on the first object is opposite to the direction of of the force on the second object.
What is equal and opposite?
