D. mechanics
• B. Gravity
When a golf ball is placed on a tee, it will remain there until a golfer strikes the ball. This example
demonstrates the part of Newton’s first law that states:
A. A body at rest remains at rest unless acted upon by an outside force.
B. A body in motion remains in motion unless a force affects it
C. A large force is required to move a large massD. Every action has an equal and opposite reaction
• A. A body at rest remains at rest unless acted upon by an outside force
Esther pushed her model sailboat across a pond. According to Newton’s first law, the sailboat should have continued
straight across the pond but didn’t. The most likely reason for this was that:
A. The force of the wind changed the sailboat’s direction of motion
B. Fish swimming near the sailboat changed its direction of motion
C. The force of the water changed the sailboat’s direction of motion
D. The sailboat increased its acceleration across the pond
• A. The force of the wind changed the sailboat’s direction of motion
A pitcher on the Cleveland Indians baseball team exerted a pushing force when throwing a pitch to a batter. The batter took a swing but missed the ball. The force that eventually
changed the motion of the ball was most likelyA. Air friction
B. GravityC. The catcher’s mittD. The swinging bat
• C. The catcher’s mitt
A CO2 cartridge was mounted on the top of a toy car; with the nozzle of the cartridge
pointing towards the back. When the gas was released the car moved 6 meters across the
room and stopped. The reaction of the car to the release of the gas was to move
A. SidewaysB. backwardC. forwardD. upward
• C. forward
A CO2 cartridge was mounted on the top of a toy car; with the nozzle of the cartridge pointing towards the back. When the gas was released the car moved 6

B. Newton’s third law - every action has an equal and opposite reaction
C. Both Newton’s 1st and 3rd lawD. Neither Newton’s 1st nor 3rd law

FINAL JEOPARDY• The acceleration rate of a free-falling object
near Earth is 9.8 m/s2. How would this compare with the acceleration rate of a free-falling object at 10km above the Earth’s surface?
The acceleration would be less because the distance between the center of the object and the center of the Earth is greater
so the gravitational force is less.
