Which Newton's Law best describes this statement, for every action there is an equal and opposite reaction?
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
How is this an example of Newton's 3rd Law?
Only the ball is applying force to the soccer player's head.
Only the soccer player's head is applying force to the ball.
An equal force are being applied by the ball and the soccer player's head on each other.
Newton's 3rd Law of Motion states...
An object at rest will remain at rest unless acted upon by an outside force and causes a change in motion
Force is equal to the mass and acceleration of an object.
For every action there is an equal and opposite reaction.
An object in motion will remain in motion at a constant speed and same direction unless an unbalanced force causes a change in motion.
Which law best describes the following statement: when a tennis ball hits the ground, then bounces back up into your hand.
Law of Inertia
Law of Acceleration
Law of Action-Reaction
A person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. Which statement best describes the backward motion of the boat as the person steps forward?
For every action there is an equal and opposite reaction.
Every mass exerts a force on every other mass.
An object at rest tends to stay at rest.
Friction opposes the motion of an object.
The rocket engines ignite and push the gases downward, what is the movement of the rocket?
The rocket moves upward
Mass of the rocket decreases
The gases cause a reduction in air resistance
The rocket moves downward
The nozzle of a rocket is pointed downward so that as fuel is ignited, the exhaust pushes downward. Why is this arrangement necessary for a rocket to function properly?
The rocket is protected from the heat of the exhaust.
Burned fuel can be collected on the ground.
As fuel is combusted, the rocket pushes the gases backward and the gases push the rocket forward.
This allows the rocket to be steered properly.
Which is an example of the law of action/reaction?
A rocket taking off from Earth
A crash test dummy flies through the windshield in a collision
A small rock skips a pond faster than a large rock
