Newtons third youtube

What does Newton's Third Law of Motion state about forces?

• 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 with the same speed and in the same direction unless acted upon by an unbalanced force.

• The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

• Objects with greater mass have greater gravitational pull.

In any interaction between two objects, how do the forces acting on each object compare?

• The forces are unequal in magnitude but opposite in direction.

• The forces are equal in magnitude and in the same direction.

• The forces are equal in magnitude and opposite in direction.

• The forces are unequal in magnitude and in the same direction.

Which of the following is an example of Newton's Third Law of Motion in action on Earth?

• A ball rolling down a hill.

• A car accelerating forward as its tires push backward on the ground.

• A book resting on a table.

• A pendulum swinging back and forth.

When an astronaut pushes a basketball in microgravity, what happens to the basketball and the astronaut?

• Both the basketball and the astronaut accelerate equally.

• The basketball accelerates significantly, while the astronaut accelerates very little.

• The astronaut accelerates significantly, while the basketball accelerates very little.

• Neither the basketball nor the astronaut accelerate.

If two astronauts of similar mass push off each other in microgravity, what will be the result?

• Only one astronaut will move.

• Both astronauts will move in the same direction.

• Both astronauts will accelerate away from each other equally.

• They will remain stationary.
