The formula for velocity is ds/dt where s (which is a function of time) is the position vector of the object at time t, and d/dt represents the derivative with regard to time.The formula for average velocity is (final position vector - starting position vector)/time.
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
acceleration = change in velocity / time
Symbol: <v>
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
99% of the object cause terminal velocity is determined from an object when it is going as fast as it will go
Always.
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
momentum
The kinetic energy of an object depends on its mass and velocity. The relevant formula is: K.E = 0.5mv2 , where m = mass and v = velocity.
final velocity-initial velocity --------------------------------- time
The simplest answer is the velocity of an object at a given time. It is also possible to determine the acceleration and displacement - but only in the same direction as the velocity. No information on motion in a transverse direction can be determined.
The formula for velocity is velocity = distance / time. It represents the rate at which an object changes its position.
