Question

The forces exerted by Earth and a skier become an action-reaction force pair when the skier pushes the ski poles against Earth. Explain why the skier accelerates while Earth does not seem to move at all.

Answer 1

Because of the earth's large mass and solid structure, the skier moves but the earth does not.

Why can't the earth be moved?

• Because the Earth is such a massive body, it cannot be moved by applying force to it. Because it cannot be moved with a small amount of force
• The amount of matter contained in an object is what gives it inertia, or the tendency of matter to remain at rest if at rest, or to continue moving in the same direction at the same speed if moving.
• The greater an object's mass, the greater its gravitational force.
• Mass is the quantity that is solely determined by an object's inertia. The greater an object's inertia, the greater its mass.
• A heavier object is more likely to resist changes in its state of motion.
• we can conclude that the skier moves but the earth does not due to the large mass of the earth and its solid structure.
