Scalar vs. Vector

Use the three words below in the word bank to complete the statements. Make sure you type them as they appear in the word bank. A scalar quantity has only magnitude.A vector quantity has magnitude and direction. Use your notes from Tuesday to help sort out which measurement is a scalar and which is a vector. Scalar Length Area Volume Speed Mass Density Pressure Temperature Energy Entropy Work Power Vector Displacement Velocity Acceleration Momentum Force Lift Drag Thrust Weight Use the word bank down below to fill in the blanks. Make sure you copy the word exactly as it appears in the word bank. 1. Displacementis distance in a given direction.2. Another word for magnitude is size.3. A vector quantity has magnitude and direction.4. A scalar quantity has only got magnitude, not direction.5. Time is a scalarquantity because it does not have direction.6. Forces are vector quantities because the have both magnitude and direction.7. Speedis a scalar quantity because it is measured in meters per second and there is no direction given.8. Distance is a scalar quantity because it gives information about how far an object moves, but not about its direction. Look at each statement decide if it describes a vector or scalar measurment. Scalar Distance: the total length an object travels. Average Speed: the total distance traveled along its path diveded by the time it takes to travel this distance. only magnitude Speed: signifies the magnitude or the object. The car travels in a circle and returns to its orginal position. Because the car travels 1000m around the circle in 20 seconds, the cars average speed will be 50 meters per second. Vector Displacement: How far and in what direction the objectis from it's starting place. Velocity: signifies the magnitude and also the direction. Average Velocity: the displacement divided by the time it take to travel this distance. The car travels in a circle and because it returns to its orginal position the car hasn't been displaced. Therefore no matter how fast the car travels around the circle, the cars average velocity will always be zero.
