Examples of scalar measurements in physics include time, temperature, speed and mass, whereas examples of vectors consist of velocity, acceleration and force. Scalars describe one-dimensional quantities that are measured with just one property. Vectors need two or more different types of measurements to describe a certain quantity.
Continue ReadingTime is a scalar that needs just one measurement to describe a quantity of seconds, minutes, hours or days. Mass is described by ounces, pounds or tons. The motion of an aircraft can be described by vectors pertaining to displacement, direction, acceleration and velocity. An airplane travels in a direction using many different scalar quantities such as speed, mass, energy and work. Direction of travel is what makes the airplane's motion a vector.
Some measurements can be confusing as to whether they are scalars or vectors. Mass is a scalar, but weight is a vector because there is direction based upon gravitational forces. Speed is a scalar measurement but velocity is a vector because it includes the direction an object travels.
Vector diagrams are shown on paper as lines with an arrow showing direction. The length of the line determines the strength of the vector. Short vectors are not as powerful as long vectors.

Full Answer >In physics, the three types of acceleration are changes in speed, direction and both simultaneously. The word "velocity" is often used in place of speed. A person can calculate the acceleration of an object by determining its velocity and the length of time it accelerates.
Full Answer >In physics, the tension on a suspended object said to be equal to the weight of the object plus or minus the mass of the object times the acceleration acting on it. In other words, this is the weight of the object plus or minus the force on it, depending on the direction in which the force is acting.
Full Answer >Terminal speed, also known as terminal velocity, is the maximum speed of a falling object when it can no longer accelerate from the gravitational pull or any constant force. This is due to air resistance negating the force of gravity acting on the object.
