Question

1. choose the best answer.

the ____ says that the total amount of energy remains the same as it changes form or moves from one object to the next.
gravitational force
axiom of friction
theorem of velocity
law of conservation of energy

1. choose the best investigation to answer the question.

which law states that an object in motion will stay in motion at the same speed and direction unless a force stops it?
newtons second law of motion
law of gravity
newtons third law of motion
newtons first law of motion

Explanation:

For question 14:
The law of conservation of energy states that energy can neither be created nor destroyed, only transformed or transferred. This matches the description in the question.
For question 15:
Newton's first law of motion (also known as the law of inertia) states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This aligns with the description in the question.

Answer:

1. law of conservation of energy
2. Newton's first law of motion
