Intro to Newton's Three Laws of Motion

What is inertia?

• The measure of an object's weight

• The force that makes objects accelerate

• The tendency of an object to change its motion

• The tendency of an object to keep doing what it’s doing

What is the equation for Newton's second law?

• F = m/a

• F = mv

• F = mg

• F = ma

What is equilibrium?

• When all forces on an object are balanced

• When an object is not moving

• When an object is at rest

• When an object is accelerating

What does Newton's third law state?

• Gravity is the only force acting on objects

• Force equals mass times acceleration

• An object in motion stays in motion

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

What is the first step in solving a problem involving forces on an object?

• Determine the object's velocity

• Draw a free body diagram

• Calculate the net force

• Measure the object's mass
