Newton's Laws of Motion Play the video to refresh your memory before you take the quiz! If a balanced force acts on an object, what will happen? They cancel each other out. No acceleration. It will accelerate in the same direction as the force. It will accelerate in the opposite direction to the force. It will accelerate at an angle of 90 degrees to the force. Unbalanced forces are not equal and cause the motion of an object to _. stay the same accelerate in the same direction as the force accelerate in the opposite direction to the force accelerate at an angle of 90 degrees to the force According to Newton's first law, an object in motion will stay in motion unless: An opposing force acts on it. It's in outer space. It stops. It remains at rest. Label each statement "1," "2," or "3" for the law of motion it illustrates. Pushing a baby on a swing is easier than pushing an adult on the same swing. Newton's Second Law Water spills from a glass carried by someone who is walking steadily and suddenly stops short. Newton's First Law When thrown with the same force, a soccer ball accelerates more than a bowling ball. Newton's Second Law A magician pulls a tablecloth out from under a dish on a table without disturbing the dish. Newton's First Law A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction. Newton's Third Law A book rests on top of a shelf and does not move until a student accidentally knocks it off. Newton's First Law When an equal force is applied to two objects of different mass, the one with less mass will accelerate faster. If a large force and a small force are applied to two objects of equal masses, the larger force makes the object accelerate faster. If the same amount of force is applied to two objects of the same mass, then both objects will have the same acceleration. What will happen if you're in a car, and the driver slams on the brake? You will stop moving. You will continue moving forward. You will gradually slow down. You will speed up. Which of the following is an opinion about friction? It occurs any time two objects are in contact It always acts in the opposite direction as motion It slows objects down too much It prevents objects on earth from staying in motion forever What causes a ball rolling across grass to slow to a stop? The rug doesn't have enough force to hold the ball. Friction resists the ball's forward motion. The rug doesn't have enough momentum to keep the ball moving. The ball isn't moving fast enough. Newton explained the relationship between force and mass in his _ Law of Motion. 1st 2nd 3rd In a collision of two vehicles of unequal mass, the occupants of the lighter vehicle would experience much higher accelerations, so they would experience much higher forces than the occupants of the heavier car.
