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. axiom of friction theorem of velocity law of conservation of energy gravitational force 15. 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 newtons third law of motion law of gravity newtons first law of motion

Explanation:

• For question 14: The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred. The other options (axiom of friction, theorem of velocity, gravitational force) do not relate to the conservation of energy.
• 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. Newton's second law is about force, mass, and acceleration ($F = ma$). Newton's third law is about action - reaction pairs. The law of gravity deals with the gravitational force between two objects.

Answer:

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