Force and Motion Study Cards

What is Newton's First Law?

• An object at rest stays at rest and an object in motion stays in motion at same direction and speed unless acted on by an unbalanced force

• Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object

• For every action there is an equal and opposite reaction

What is Newton's 2nd Law?

• An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force

• Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object

• For every action there is an equal and opposite reaction

What is the 3rd Law of Motion?

• For every action there is an equal and opposite reaction

• An object at rest stays at rest and an object in motion stays in motion

• Acceleration is produced when a force acts on a mass
