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 mass D. Every action has an equal and opposite reaction A. A body at rest remains at rest unless acted upon by an outside force

A. The force of the wind changed the sailboat’s direction of motion 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

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.
