What is force? This is what represents a stronger force. What is a longer arrow? Acceleration occurs under what 3 scenarios. What is increase speed, decrease speed, or change direction? This is the force that opposes motion. What is friction? This happens when an unbalanced force acts on an object. What is motion? This is what keeps a satellite in orbit. What is centripetal force? This is the tendency of an object to resist a change in motion. What is inertia? This is what stops an object from moving. What is an unbalanced force? This is what happens when 0 N force acts on a stationary object. What is an object stays at rest. st 1 State Newton’s law in its entirety. What is an object at rest will remain at rest, and an object in motion will remain in motion unless an unbalanced force acts on it? These are the 3 factors that are related in nd Newton’s 2 law. What is acceleration, force, and mass? This the formula to calculate force and the unit? What is a force = mass x acceleration? What is Newtons (N). This is the formula to calculate acceleration and the unit for acceleration. What is acceleration = net force ÷ mass? 2 What is m/s These are the two ways to increase your acceleration. What is increase force or decrease mass? This is the formula to calculate weight on Earth. What is force = mass x 2 9.8m/s ? A hummer will have more of this due to its larger mass. What is more momentum? State Newton’s 3rd law of motion. What is for every action, there is an equal and opposite reaction? State the following reaction force. If “A” exerts a force on “B”, then …. What is “B” exerts an equal but opposite force back on “A.” This is the formula to calculate momentum and the unit for momentum. What is momentum = mass x velocity. Momentum’s unit is kg x m/s. Under what condition would you divide the momentum between two objects. What is when they connect after the collision? This is the force that is equal in size but opposite in direction. What is a balanced force? A force you need to overcome to start an object moving. What is static friction? This is the upward force that acts on objects as they fall through the air. What is air resistance? When students are playing tug of war and the flag moves, you know the forces are …. What is unbalanced? This is what happens to momentum when two objects collide. What is momentum transfers.
