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 the direction is northeast. The vector A→−B→ has the same ...
How would a graph of motion with a constant velocity differ? Velocity and acceleration: The speed of a body is the magnitude that defines how fast a body can change its position in an interval of time, this is what is known as the derivative of a function. Velocity is the derivative ...

The rate of change of velocity of an object with respect to time is termed as the 'acceleration' of the object. If the velocity of the object is plotted against time, the slope of the tangent to a point on the graph gives the acceleration of the ...
