Newton's Laws and Motion Concepts

What is motion relative to?

• The stars

• The sun

• The moon

• The observer's point of view

What is the main idea of Newton's first law?

• Objects are always in motion

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

• Objects in motion stay in motion unless acted upon by an outside force

• Force equals mass times acceleration

Which formula represents Newton's second law?

• F = mg

• F = mv

• F = ma

• E = mc^2

What is the force that always tries to stop motion when two surfaces touch?

• Gravity

• Friction

• Magnetism

• Electricity

What is the difference between mass and weight?

• Mass changes with location, weight does not

• Mass is the amount of matter, weight is the force of gravity on that matter

• Mass and weight are the same

• Mass is the force of gravity, weight is the amount of matter
