Inquiry Science (Questions and Answers)

Inquiry Science An object's resistance to any change in its motion is the of ---------the object. inertia A tugboat is pushing a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat. Which force would most likely allow the tugboat to move the barge into the harbor? -4500 N Based on the tug of war pictured below, what is the net force? 10 N The graph represents velocity vs. time for Carla. Which best describes the graph? Carla slowed down in the beginning of her trip, stopped, and then sped up. Tyler and his family drove from Atlanta to Baltimore. They traveled a total of 678 miles over 2 days. What is the reference point in this scenario? Atlanta In a car, how does an air bag minimize the force acting on a person during a collision? It increases the time it takes for the person to stop. The diagram shows organisms a diver observed during an ocean dive. What did the diver most likely use as a reference point to describe the position of the squid? the ocean surface Scientists launch a rocket, and they monitor its acceleration and the force exerted by its engines. As the rocket gets higher, the monitors show that the acceleration of the rocket is increasing but the force exerted stays the same. How do Newton's laws explain why the scientists could expect this to happen? The mass of the rocket decreases as fuel is burned, so the acceleration increases The table shows the relationship between the masses of two objects, the distance between the two objects, and the gravitational force between the objects. Which conclusion is supported by the data in the table? An increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass. -- -- Sayid made a chart listing data of two colliding objects. According to the law of conservation of momentum, what is the missing value in the chart? 6 Kai was 200 meters north from his house when he remembered he had to take some books to the library. It took him 200 seconds to do the round trip. Which best describes Kai's roundtrip? His speed was 2 m/s, and his velocity was 0. A football player has a mass of 65 kg and is moving with a velocity of 5 m/s. What is the player's momentum? 325 kg • m/s Which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving? a 75kg dining table force is a vector that has both_______ and direction. magnitude
