Question

caleb skates on his rollerblades at a skate park near his home. which statement describes how newtons first law of motion is involved in this interaction? the ground exerts the same magnitude of force onto calebs rollerblades that his rollerblades exert onto the ground. caleb will continue rollerblading forward until he pushes off the ground to turn. caleb has to push harder on the ground to accelerate when he is wearing his backpack than when he is not.

Explanation:

Newton's first law states that an object in motion will stay in motion with a constant velocity unless acted upon by an un - balanced force. Caleb will keep moving forward in a straight line (continue rollerblading forward) until a force (like pushing off the ground to turn) acts on him. The first option is Newton's third - law (action - reaction), and the third option is Newton's second law ($F = ma$).

Answer:

Caleb will continue rollerblading forward until he pushes off the ground to turn.
