Concept 3 Newton's Laws

What is the definition of the Newton's Law of Inertia?

• The stronger forces will cause faster motion, but heavier objects need more force to make motion
• There is an equal and opposite reaction. the direction of the force of an action is the opposite direction
• Objects at rest will stay at rest and objects in motion will stay in motion until it is acted by the outside force

What is not an everyday thing that is related to Newton's first law?

• An asteroid floating in space.
• A person sliding a book.
• A light bulb.

How is gravity related to Newton's law of inertia?

• A person buying a video game.
• Gravity pulls objects further into an object's gravitational field.
• A person catching a football.

How is friction related to the law of inertia?

• Friction is the unbalanced force that acts on an object.
• A football player throws the ball to another player.
• A person washing a dog.

How can unbalanced forces effect an object at rest?

• It will be moved from it's resting position.
• They won't effect it.
• They will increase the mass of the object.

What is the definition of Newton's second law?

• There is an equal and opposite reaction. the direction of the force of an action is the opposite direction
• Objects at rest will stay at rest and objects in motion will stay in motion until it is acted by the outside force
• The stronger forces will cause faster motion, but heavier objects need more force to make motion.

How could friction affect the motion of an object?

• An planet rotating in space.
• A player throw a basketball to the pla
• Slows it or cause it to stop.

How is net forced been calculated?

• Forces going in the same direction are added, and going in the opposite direction are subtracted.
• Force= mass x acceleration.
• Pythagorean theorem: A squared plus B squared plus C squared.

What is the definition of net force?

• An increase in the rate or speed of something.
• F=MxA
• A net force is a the sum of the forces acting on an object.

What is the definition if acceleration?

• The sum of the forces acting on an object.
• An increase in the rate or speed of something.
• Slows it or cause it to stop.
