Game Board A change in a moving object’s speed or direction What is acceleration? Game Board An object that appears to stay in place to help you detect the motion of another object What is a reference point? Game Board final velocity – starting velocity time it takes to change What is the formula for acceleration? Game Board The formula for speed What is: Speed = distance time Game Board A push or a pull on an object. What is a force? Game Board The total force after all forces have been added together. If the question is correct--Bonus!!!!! (100pts) What is net force? Game Board The net force when an object is being pushed with 10N to the right, and pulled with 5N to the right What is 15N to the right? Game Board This can cause an object’s motion to change speed and/or direction What is an unbalanced force? Game Board When the net force is anything but 0N this type of force is present. What is an unbalanced force? Game Board This force always opposes motion What is friction? Game Board This opposing force keeps an object staying still even though it is being pushed or pulled What is static friction? Game Board While an object is moving, the frictional force is referred to as What is kinetic friction? Game Board A piano on wheels experiences this type of friction What is rolling kinetic friction? Game Board This type of friction occurs when a liquid or gas is used, possibly to reduce friction What is fluid kinetic friction? Game Board The force of attraction between objects What is gravity? Game Board The measure of gravitational force exerted on an object What is weight? Game Board A measure of the amount of matter in an object. It does not change when an objects’ location changes What is mass? Game Board According to Newton’s Law of Universal Gravitation, the gravitational pull is greater between objects that … What is have more mass or are closer together? Game Board He came up with the Law of Universal Gravitation Who is Sir Isaac Newton? Game Board This states that gravitational force is related to mass and distance. What is the law of universal gravitation? Game Board A runner traveling at 6 m/s South slows to a stop at the base of a hill after 4 s. What is the runner’s acceleration? Game Board This force is caused by the rubbing together of microscopic hills and valleys of objects. What is friction? Game Board A swimmers velocity changes from 10m/s South to 2 m/s South. The type of acceleration occurring is… If the question is correct--Bonus!!!!! (100pts) What is negative acceleration or deceleration? Game Board Describe speed and velocity and state the difference between the two. What is speed is the distance divided by time, while velocity is speed in a direction? Game Board Make your wager Find a runner’s acceleration if his initial rate was 2 m/s, his final rate was 6m/s and this occurred over 2 seconds.
