Scalars Study guides, Class notes & Summaries

vectors - forces with magnitude and direction scalars - forces with magnitude but no direction contact forces - requires contact eg friction non contact forces - doesnt require contact eg gravity mass and weigth - directly proportional weight - mass x gravitational field strength gravitational field strength on earth - 9.81 resultant force - the overal force acting on an object if a resultant force moves and object - work is done scale drawings - triangular drawings, finding the hypoten...

Scalars Quantities that are fully described by a magnitude alone. Vectors Quantities that are fully described by both a magnitude and a direction. Distance Scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement Vector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed Scalar quantity that refers to "how fast an object is moving." Velocity V...

Prefix units Uncertainties Adding or subtracting- Add the absolute uncertainties Multiplying or dividing- Add the percentage uncertainties Raising to a power- Multiply the percentage uncertainties by the power Percentage uncertainty in the gradient uncertainty = ½(line of best fit - line of worst fit) Percentage uncertainty = uncertainty ÷ gradient of best fit line (× 100) Speed Rate of change of distance Displacement The distance an object has travelled in a given direction Veloc...
