Question

1.) What is the change in the force of gravity between two objects if a) the masses of both objects are doubled but the distance between their centers of mass remains the same, and b) if the masses of both objects remained the same but the distance between them were halved?

2.) Two golf balls are hit off a tee at the same initial speed but at different launch angles -- 30º and 45º. Which golf ball will travel farther? Explain.

3.) Students in a lab roll a steel ball off the edge of a table. They measure the speed of a horizontally launched ball to be 2.0 m/s. They also know that if they drop the ball from rest at the same height it would take 0.5 seconds to reach the floor. How far from the edge of the table should they place a target so that the ball will hit it when it lands?

Explanation / Answer

1.

Force is directly proportional to the product of the masses and inversely proportional to the square of the distance. so

a) if the masses are doubled then the force increases 4 times.

b) if the distance is halved then the force increases by 4 times.
