#2 Force and Motion Vocab Quiz

Law of Conservation of Momentum

• the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton's laws of motion
• the resistance to any change in the state of motion of any physical object
• any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them

Displacement

• the length and direction of a straight line between two locations, or positions . Since displacement considers only the length and direction of a straight line, it doesn’t depend on the actual path of a moving object .
• measures the rate at which an object moves along a path . Unlike velocity, speed is not considered to have a direction
• the total amount of matter of an object

Mass

• the total amount of matter of an object
• measures the rate at which an object moves along a path . Unlike velocity, speed is not considered to have a direction
• a measure of the length of a path that a moving object travels

Friction

• the force that resists motion between two surfaces
• a push or pull on an object . Force can be the result of contact, such as when you push a book across your desk
• the resistance to any change in the state of motion of any physical object

Speed

• the resistance to any change in the state of motion of any physical object
• measures the rate at which an object moves along a path . Unlike velocity, speed is not considered to have a direction
• the force of attraction that exists between any two or more masses

• the total amount of matter of an object

Inertia

• the resistance to any change in the state of motion of any physical object
• the force that resists motion between two surfaces
• the force of attraction that exists between any two or more masses

BONUS (10pts) Newton's second law can be summarized as a formula. Choose the correct description and formula for newton's second law. two options are correct

• F = m*a
• F = m/a
• A net force acting on an object causes the object to accelerate in the direction of the net force.
• every action has an equal and opposite reaction.
