Question

a fuel hauling truck accelerates from a stop as it leaves a gas station. match each of newtons laws of motion to the statement it best describes. newtons first law of motion newtons second law of motion newtons third law of motion when the truck accelerates forward, the fuel in the tank moves towards the back of the tank. the more fuel in the tank, the more force is required to accelerate the truck at a given rate. the fuel exerts a backward force on the tank that is equal to the forward force the tank exerts on the fuel.

Explanation:

• Newton's first law (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. When the truck accelerates forward, the fuel in the tank moves towards the back of the tank because the fuel has inertia and wants to stay in its original position.
• Newton's second law is $F = ma$ (force equals mass times acceleration). The more fuel in the tank (more mass), the more force is required to accelerate the truck at a given rate.
• Newton's third law states that for every action, there is an equal and opposite reaction. The fuel exerts a backward force on the tank that is equal to the forward force the tank exerts on the fuel.

Answer:

• When the truck accelerates forward, the fuel in the tank moves towards the back of the tank: Newton's first law of motion
• The more fuel in the tank, the more force is required to accelerate the truck at a given rate: Newton's second law of motion
• The fuel exerts a backward force on the tank that is equal to the forward force the tank exerts on the fuel: Newton's third law of motion
