OAR Exam 2024 with 100% correct answers

scalar - correct answer quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector - correct answer quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) - correct answer the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) - correct answer the speed and direction of a body's motion, the rate of change of position (an airplane flies south at 400 knots). Speed - correct answer a scalar equal to the magnitude of the velocity vector. Acceleration (a) - correct answer the rate and direction of a body's change of velocity (gravity accelerates bodies toward the center of the earth at 32.174 ft/s2). force (F) - correct answer a push or pull exerted on a body (1,000 lbs of thrust pushes a jet through the sky). Mass (m) - correct answer the quantity of molecular material that comprises an object. Volume (v) - correct answer the amount of space occupied by an object
