.During a spacewalk, if an astronaut loses his connection with the space station, he would slowly drift away
from the station. Which action might help him get back to the station?
throwing a heavy tool toward the station
dropping all of his tools to reduce his weight
rolling into a ball to reduce friction and increase his speed
throwing a heavy tool in the direction that he is floating
When a fish swims forward, its fins push backward against the water. What would happen if the water did not exert an equal force in the opposite direction?
The fish would swim faster.
The fish would swim slower.
The fish would not move forward.
The fish would move backward in the water.

When you dribble a basketball on a court, it returns to your hand even though you have pushed it away from you. Which of the following statements explains why the ball doesn’t stay on the ground?
Gravity is not strong enough to keep the ball near the ground.
The ground pushes the ball back toward you harder than you pushed it away.
The ground pushes the ball back with the same force that the ball pushes the ground.
The ball has enough recoil in it so that the force used to push the ball down is multiplied.
How do forces act on an object?
They usually act alone
They act in pairs
When a cannon fires a cannonball we observe Newton's third law. Which is the reaction force?
The cannon moving forward
the cannon moving backwards
the cannonball moving backwards
The cannonball moving forward
Action-reaction forces never cancel each other out because....
they act on different objects
they act on the same object
they do not act on objects
A baseball bat hits a baseball with a force of 100 Newtons. What is the force and its direction exerted by the ball on the bat?
100 Newtons, same direction
100 Newtons, opposite direction
200 Newtons, opposite direction
200 Newtons, same direction

If the person is pushing backwards with the paddle, why do they move forward?
The person will actually move backwards, they need to paddle the other way
The water pushes back with an equal and opposite force
The person is pushing harder than the water
The water pushes back with a greater force than the person
When the person pushes on the wall, and the wall pushes back, why does the person move and not the wall?
The wall has more mass
The person is pushing harder than the wall
The wall is pushing harder than the person
The skateboard is pushing on the person
A book rests on a table. The force of gravity pulls down on the book with a force of 20N. What prevents the book from falling down into the ground?
The table and the book are pushing back with an acceleration of 9.8m/s2.
The table pushes back up on the book with a force greater than 20N
The inertia of the book is equal to the inertia of gravity
The table pushes back up on the book with an equal and opposite force of 20N
