![]() Try to have a minimum gap of 1/8 inch between the frame and any spacers (or wheels) in order to decrease any rubbing friction. If the car moves forward, it will gain additional distance after stopping, but there is no way to predict where the center of mass will come to rest when the car stops. Winding the string around the axle pulls back the snap arm and releasing the snap arm pulls the string, turning the wheels.Īs the center of mass begins to fall towards a more stable position the wheel begins to rotate, causing the car to move either backward or forward. Power to drive the wheels is provided by a mousetrap to which a wand and string is attached to the snap arm. How does the mousetrap make the car move? – Newtons second law: Acceleration is produced when a force acts on a mass. The mouse trap car relates to Newtons first law because the car does not move until the force of the mousetrap moves it and then it doesn’t stop until it hits something or until gravity finally stops it. How does a mousetrap car demonstrate Newtons laws? Therefore, to increase your car’s speed, you can reduce the length of the lever arm attached to the mousetrap. If you haven’t realized it yet, increasing the length of the lever arm attached to the mousetrap, increases the total mechanical advantage of the car. 24 What is the fastest mousetrap car design? How is Newton’s third law used in a mousetrap car?Ī car is propelled forward because the drive wheels push on the road and the floor pushes back against the wheels of the car causing the car to move.
