WW-Newtons Laws

What do Newton's laws of motion describe?

• The relationships between forces, matter, and motion

• The speed of light

• The structure of atoms

• The properties of gases

What is inertia?

• The tendency of an object to resist a change in motion

• The force that pulls objects toward the Earth

• The speed at which an object moves

• The energy stored in an object

What does friction do?

• Opposes motion between objects that are touching

• Increases the speed of moving objects

• Reduces the mass of objects

• Changes the color of objects

What is acceleration?

• The rate at which velocity changes over time

• The distance traveled per unit time

• The force applied to an object

• The mass of an object

What does Newton's first law of motion state?

• An object will not move or change its motion unless acted upon by an unbalanced force

• The acceleration of an object depends on its mass and the net force applied

• For every action, there is an equal and opposite reaction

• Objects in motion stay in motion indefinitely

What does Newton's second law of motion state?

• The acceleration of an object depends on the mass of the object and the net force applied

• An object will remain at rest unless acted upon by a force

• For every action, there is an equal and opposite reaction

• Objects in motion stay in motion indefinitely

What does Newton's third law of motion state?

• Whenever one object applies a force on a second object, the second object applies an equal force on the first object

• An object will remain at rest unless acted upon by a force

• The acceleration of an object depends on its mass and the net force applied

• Objects in motion stay in motion indefinitely

What is gravity?

• The universal attraction that exists between all objects

• The force that opposes motion

• The energy stored in an object

• The speed of an object

What is magnetism?

• A noncontact force

• A type of friction

• A measure of mass

• A form of energy

What is weight?

• A measure of the force of gravity acting on an object

• The mass of an object

• The speed of an object

• The energy of an object
