While trying to explain a physics concept, a student said, "Stuff keeps doing what it's doing unless something messes with it." What law was the student summarizing? Explain your answer.Your answerWhen a soccer player kicks a ball, the ball accelerates. Explain what causes this acceleration in terms of forces.Your answerDescribe three examples from sports in which a force changes the velocity of an object or a person.Your answerExplain which has greater inertia; a speeding car or a jet airplane sitting on the runway.Your answerDo forces always cause motion, explain?Your answer
Question
Answer:
1) Newton's first law of motion2)The soccer ball accelerates because of the force the soccer player exerts on the ball.
4)Inertia is the act of not doing anything. Therefore, the jet airplane sitting on a runway has the greatest inertia because it is literally doing nothing.
5)Forces DO NOT always cause motion. friction is a force that goes against a motion, this is a resistant force.
Sorry but I wouldn't want to inaccurately answer #3, so I didn't do it.
