Scalar - Mass is a , Vector - Acceleration, Deceleration - Means slowing down, 0 N - If the object is not moving, the resultant force must be, > 0N - If the object is changing velocity, the resultant force must be, F=ma - Equation that links force, mass and acceleration, Increases - How does air resistance change as speed increases, Decreases - How does friction change as speed decreases, Equal - At terminal velocity, air resistance and weight are, Bar Chart - If you have categoric data, like eye colour or shoe size, you should plot a , Scatter graph - If you have continuous data, like height or reaction time, you should plot a, Thinking Distance - Affected by alcohol, drugs, distractions, Braking Distance - Affected by tyre tread, brake quality, weather conditions, Thinking and Braking distance - Affected by car speed, The gradient of the graph - How do you find acceleration from a velocity vs time graph, The area under the graph - How do you find distance travelled from a velocity vs time graph, m/s - Unit of speed, m/s^2 - Unit of acceleration, Constant gradient >0 - If the person is walking at a steady, constant speed, the distance time graph would have a , Increasing gradient (curve) - If someone was accelerating, their distance time graph would have an , Size (magnitude) and direction - Vector quantities have a, Size (magnitude) - Scalar quantities have a , Accelerate - If the forwards force was 200N, and the backwards force was 80N, the object would, Go at a constant velocity - If the forwards force was 200N, and the backwards force was 200N, the object would, Air Resistance - Which force increases as a skydiver is accelerating through the air, Speed - Distance / Time, Acceleration - Change in velocity / Time, Normal Contact Force - Force exerted at 90 degrees to all surfaces in contact, Weight - Force caused by the pull of the Earth's gravitational field on your mass, Directly proportional - Acceleration is _____ to resultant force,
