TCI Gravity

Newton's laws of motion and of universal gravitation apply to the star and planets pictured here. Suppose Planet 3 is similar to Earth. Check each of the following TRUE statements.

• The weight of an object measured on Planet 3 is a result of gravity.

• Because of gravity, Planet 3, which is smaller than the star, remains in orbit around the star.

• Small objects near Planet 3 experience much less acceleration the closer they get to the surface of the planet.

The main reason a baseball comes down when a boy tosses it up into the air is —

• magnetism is pulling the ball down

• the boy cannot see to catch it

• gravity is pulling down on the ball

• gravity pushes the ball in the air
