When two objects are near each other, how would increasing one object’s mass affect it?

• The gravitational force of the object would increase.

• The mass of the object would be stronger than gravity.

• The weight of the object would decrease.

• The shape of the object would change.

Which statement supports Newton’s first law of motion?

• Planets with a greater mass will orbit more quickly than smaller planets.

• Planets can move at a varying speed due to forces exerted in space.

• Planets with more inertia will not be impacted by the Sun’s gravity.

• Planets can change the direction of their own orbital path.
