The measure of a gravitational force on an object. A push or pull, measured in Newtons. A change in position over time when compared to a reference point. D/T or Distance divided by Time. A substance applied to a surface to reduce friction. A type of friction involving a liquid or a gas. This occurs when an object speeds up, slows down, or changes direction. It is the change in velocity over time. Describes the relationship between force, mass, and distance. (Vf – Vi)/T or (final velocity – initial velocity)/time The type of friction that holds a non-moving object in place. The unit of measure of mass. A force that opposes (slows down) motion between two surfaces that are touching. The speed and direction of an object. When these forces act on an object, there is a change in motion. The amount of matter in an object. A force between two objects due to their masses and the distance between them. When you observe motion, you compare a moving object to something that appears to stay in place. The object that appears to stay in place is called a ______________. The type of friction that involves wheels or tires. When these forces act on an object, there is no change in motion. Total distance traveled divided by total time. The unit of measure for force. This is found by combining all of the forces acting on an object. The type of friction between two objects that rub or slide against each other. One example of a unit of measure for acceleration. Which is usually a SMALLER force? Sliding Friction or Rolling Friction This object is… (Circle One): Speeding up/Accelerating This object is… Moving at Constant Speed Stopped (Circle One): Speeding up/Accelerating Moving at Constant Speed This object is… Stopped (Circle One): Speeding Up/Accelerating Moving at Constant Speed Stopped Which object is moving at a higher speed? (Circle One): The dashed line The solid line Look at the following diagrams and find the net force on each object. Write the size and direction (up, down, left, or right) of the net force on each object. a. Size of Net Force: 3 N Direction of Net Force (Circle One): Up Down Left Right b. Size of Net Force: 5 N Direction of Net Force (Circle One): Up Down Left Right c. Size of Net Force: 4 N Direction of Net Force (Circle One): Up Down Left Right List an example of each type of friction (Static, Sliding, Rolling, Fluid) that you experience when you ride your bicycle. Static Friction Sliding Friction Fluid Friction Rolling Friction Feet stay on pedals Brakes slide on tires Wind rushes past you Tires roll on ground
