Velocity is a vector quantity: it has both magnitude and direction. Speed is the magnitude of the velocity: no direction is associated with speed. 2. (b) 3. (c) 4. 144 ft; 96 ft/s downward; zero 5. 4 s; 12 ft 6. 450 m/s2 7. The magnitude of A→+B→ is 32 units and ...
angular velocity is the time rate at which an object rotates or revolves about an axis. q2 why is angular velocity a vector? angular velocity is a vector quantity because it has both magnitude and direction. q3 can angular velocity be negative? by convention, positive angular velocity indicates...
Describe what is meant by velocity? Explain why velocity is a vector quantity. How to calculate velocity? Explain why motion in a circle involves constant speed but changing velocity. Distance and Displacement, Speed and Velocity Examples:
Velocityis a vector quantity that indicates displacement, time, and direction. Unlike speed, velocity measuresdisplacement,a vector quantity indicating the difference between an object's final and initial positions. Speed measures distance, a scalar quantity that measures the total length of an object'...
Which is vector speed or velocity? Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, whilevelocity is a vector quantity– it is the speed of an object in a particular direction. Can you move with constant velocity but not constant speed?
Velocity, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point
Velocity is a VECTOR quantity –it has magnitude & direction. Average Velocity is the displacement of an object divided by the time interval. SPEED VELOCITY 9 Equations SPEED VELOCITY 10 Problem Solving RULES:Must draw a picture (motion diagram) that includes vector arrows representing speed/ve...
Velocity is often used interchangeably with the scalar quantity of speed, but the two terms have distinct differences. Speed measures the distance traveled per unit of time and ignores the direction traveled. Velocity, however, is a vector quantity that considers change in position over time (magni...
In physics, the angular velocity is a vector quantity which specifies the angular speed of an object and the axis about which the object is rotating. The SI unit of angular velocity is radians per second, although it may be measured in other units such as degrees per second, revolutions per...
Seawater can be regarded as a “chunk object” and the motion state of its particle is different along with the position in space (x, y, z) and the time (t). The velocity is a physical quantity both with size (scalar) and direction (vector) to describe motion (state). Therefore, th...
