Newton's 3rd Law

Newton's 3rd Law states

• Objects in motion stay in motions and objects at rest stay at rest

• Force is equal to mass times acceleration

• For each action there is an equal and opposite reaction

When you shoot an arrow. The action is the bowstring against the arrow. So the reaction is...

• Air resistance against the bow

• Arrow's push against the bowstring

• Grip of the archer's hand on the bow

For every action, there is an equal and opposite reaction

• Law of Inertia

• Newton's 2nd Law

• Newton's 3rd Law

• Newton's 4th Law

If the bowstring applies a force to the arrow... the arrow does what?

• Applies the SAME force back on the bowstring

• Applies a WEAKER force back on the bowstring

• Applies a STRONGER force back on the bowstring

If a 65 kg astronaut exerts a force with a magnitude of 50 N on a satellite that she is repairing, the magnitude of the force that the satellite exerts back on her is

• 50 N

• 0 N

• 50 N LESS than her weight

• 50 N MORE than her weight

If a 75 kg astronaut exerts a force with a magnitude of 5 N on a satellite that she is repairing, the magnitude of the force that the satellite exerts back on her is

• 5 N

• 10 N

• 5 N LESS than her weight

• 5 N MORE than her weight

Baseball kid catches a ball. The action is the ball hitting the player's glove. The REACTION is...

• the glove's force exerted back on the ball

• the player's grip on the glove

• the friction of the ground on the kid's shoes

Action is dog to cat. My reaction would be

• Cat to mouse

• Cat to dog

• Dog to cricket

Kid hits a ball with a bat. ACTION is force of the bat against the ball. REACTION is the...

• Ball against the bat

• Bat against face

• Ball against face

A volleyball player hits the ball with a force of 1000 N. The ball exerts a reaction force against the defense with a force of...

• 1000 N

• Less than 1000 N

• More than 1000 N
