Newton's Laws of Motion Quiz

Newton's First Law of Motion (Law of Inertia)

• An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
• Inertia is the tendency of an object to resist a change in its motion. Greater mass means greater inertia.
• Essentially, objects resist changes to their state of motion.
• A stationary object will not move unless a force is applied to accelerate it.
• A moving object will continue to move in the same direction at the same speed unless a force causes a change.

Newton's Second Law of Motion

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
• This is often expressed mathematically as: F = ma, where F is force, m is mass, and a is acceleration.
• A larger force results in a larger acceleration.
• A larger mass results in a smaller acceleration for the same force.
• The net force is the vector sum of all forces acting on an object.
• This law explains how changes in force affect motion.

Newton's Third Law of Motion (Law of Action-Reaction)

• For every action, there is an equal and opposite reaction.
• Forces always come in pairs.
• If object A exerts a force on object B, then object B simultaneously exerts an equal but opposite force on object A.
• These forces act on different objects and are equal in magnitude but opposite in direction.
• The action and reaction forces do not cancel each other out because they act on different objects.
• Examples include: a rocket propelling itself by expelling hot gas, a person jumping off a boat.
• These pairs of forces cannot be the same force in the same object.
