Laws of Motion Again

What is the first law of Motion

• Object at rest, remains at rest

• Force = mass * acceleration

• For every force, there is an equal and opposite force

What is the Second law of Motion

• Object at rest, remains at rest

• For every force, there is an equal and opposite force

• Force = mass * acceleration

What is the Third law of Motion

• Object at rest, remains at rest

• Force = mass * acceleration

• For every force, there is an equal and opposite force

What is Inertia?

• The tendency of an object to remain in motion

• The tendency of an object to remain at rest
