WebIn the equation V = d/t, V is the velocity, d is the distance, and t is the time. Determine the object’s acceleration by dividing the object’s mass by force and multiply the answer by the time it took for it to accelerate. For example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s. WebIn physics, you can calculate the velocity of an object as it moves along an inclined plane as long as you know the object’s initial velocity, displacement, and acceleration. Just plug this information into the following equation: The figure shows an example of a cart moving down a ramp. You can use the formula with the information in the ...

WebThe applied force converts the stored potential energy of the stationary object to kinetic energy to perform work. That’s why using the work-energy formula; we can calculate speed from force and mass. The work formula is, W= Fd. Since work done of an object is its gaining in kinetic energy KE= (1/2)mv 2. (1/2)mv 2 =Fd. WebFigure 3.30 (a) Velocity of the motorboat as a function of time. The motorboat decreases its velocity to zero in 6.3 s. At times greater than this, velocity becomes negative—meaning, the boat is reversing direction. (b) Position of the motorboat as a function of time. At t = 6.3 s, the velocity is zero and the boat has stopped. At times ...

WebSpeed is a scalar and velocity is a vector. Speed gets the symbol v (italic) and velocity gets the symbol v (boldface). Average values get a bar over the symbol.
