Forces and Newton's Second Law

Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.

Which of these best states Newton's Second Law?

• The greater the mass of an object the greater the force needed to change its motion.

• The greater the mass of an object the less force needed to change its motion.

• The mass of an object does not effect the force needed to change its motion

The reason a tennis ball and a solid ball will accelerate at the same rate during free fall, in the absence of air resistance is that

• they have the same mass.
• the ball with the larger force has the smaller mass.
• the ball with the larger force also has the larger mass.
• none of the above.
