• It doubles

• It quadruples

• It remains the same

• One-third

• One-sixth

• Three times

A satellite orbits Earth at a constant height. What happens to the gravitational force acting on it if its mass is doubled?

• It remains constant

• It halves

• It doubles

• It quadruples

If the radius of Earth were doubled but its mass remained the same, the gravitational acceleration on its surface would be:

• Halved

• Doubled

• Quartered

• Unchanged

The gravitational force between two objects is 100 N. If the distance between them is halved, the new gravitational force is:

• 25 N

• 50 N

• 200 N

• 400 N

A person’s weight on Earth is 600 N. What would their weight be on a planet with the same mass as Earth but twice the radius?

• 150 N

• 300 N

• 600 N

• 1200 N

Which force must be overcome to start an object sliding on a surface?

• Static friction

• Kinetic friction

• Normal force

• Centripetal force

If a 50 N force is applied to a box but it does not move, the force of static friction is:

• Greater than 50 N

• Equal to 50 N

• Less than 50 N

• Dependent on the surface area

The coefficient of kinetic friction is always:

• Equal to static friction

• Greater than static friction

• Less than or equal to static friction

• Independent of the materials involved
