 Side A Side B 1 What is the definition for force? a force is anything that makes apush or a pull to make an object accelerate or decelerate. 2 What is a constatn speed? When an object travels in an equal amount of time and distance. 3 The more __________ and object has the harder it is to stop. Momentum. 4 What is the equation for momentum? p=mv 5 What is speed measured in? distance and time. 6 What are the two types of forces? Balance and unbalanced. 7 When forces are unbalanced, what occurs? Acceleration. 8 When forces are balanced, what can happen? Either there is no movement, or the movement is at a constant speed. 9 How many types of friction are there? Four (4) 10 What is the strongest form of friction? Static Friction 11 What is static friction? A type of friction that holds an object in place. 12 What is sliding friction? When one surface slides against another. 13 What is rolling friction? A type of friction where one surface rolls against another. 14 What is fluid? Fluid is a liquid or a gas. 15 What is fluid friction? Fluid friction is friction with liquid and gas. 16 Gravity depends on __________ and _________. mass, distance 17 What is Newtons first law of motion? An object in motion tends to stay in motion.
