Which of these factors affect the force of gravity between two objects?

Distance between the two objects

Which of the following is NOT an example of Newton's 3rd Law?

A soccer ball at rest being kicked

Would a heavier object accelerate quicker or slower than a lighter object?

Slower because mass has an indirect relationship with accel.

Which of Newton's Laws says "a body at rest tends to stay at rest."

Newton's 1st Law, Newton's Law of Universal Gravitation

A 30kg donkey & 100kg elephant are running towards you at 10m/s. Which would be easier to stop?

The donkey because it has less momentum
