What is Newton's 3rd Law of Motion?

• For every force, there is a corresponding force in the same direction.
• An object in motion stays in motion unless acted upon by a force.
• For every action, there is a proportional reaction.
• For every action, there is an equal and opposite reaction.

What does the 3rd Law of Motion Mean?

• For every action, there is a greater reaction.
• Objects in motion will stay in motion indefinitely.
• An object at rest will remain at rest unless acted upon by a force.
• For every action, there is an equal and opposite reaction.

What is happening in Newton's 3rd law of motion that keeps a person stay seated on a chair?

• The chair exerts an equal and opposite force upward, balancing the person's weight.
• The chair moves downward to accommodate the person's weight.
• The person pushes down harder on the chair, causing it to sink.
• The chair absorbs all the weight without any force acting on it.

What is Newton's 2nd Law of Motion?

• The force acting on an object is equal to its mass times its velocity.
• An object in motion will stay in motion unless acted upon by an equal force.
• The acceleration of an object is constant regardless of the net force applied.
• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Why does a heavy object not move very much when a smaller object pushes it?

• A heavy object does not move much because it has greater inertia, making it resistant to the force applied by a smaller object.
• A heavy object moves quickly due to its size and shape.
• The smaller object has more mass, allowing it to push the heavy object easily.
• A heavy object moves easily because it is lighter than the smaller object.

Who Discovered The 3 Laws of Motion?

• Albert Einstein
• Sir Isaac Newton
• Niels Bohr
• Galileo Galilei

What is Newton's 1st Law of Motion?

• An object will change its direction only when a force is applied.
• An object in motion will eventually stop without any force.
• An object will accelerate if no forces act on it.
• An object will remain at rest or in uniform motion unless acted upon by an external force.
