Kinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi).

In physics, the definition of time is simple— time is change, or the interval over which change occurs. It is impossible to know that time has passed unless something changes. The amount of time or change is calibrated by comparison with a standard. The SI unit for time is the second, abbreviated s.

In this part of Lesson 6 we will investigate the process of using the equations to determine unknown information about an object's motion. The process involves the use of a problem-solving strategy that will be used throughout the course. The strategy involves the following steps: 1. Construct an informative diagram of the physical situation. 2. Id...
Ima Hurryin is approaching a stoplight moving with a velocity of +30.0 m/s. The light turns yellow, and Ima applies the brakes and skids to a stop. If Ima's acceleration is -8.00 m/s2, then determine the displacement of the car during the skidding process. (Note that the direction of the velocity and the acceleration vectors are denoted by a + and ...
Ben Rushin is waiting at a stoplight. When it finally turns green, Ben accelerated from rest at a rate of a 6.00 m/s2 for a time of 4.10 seconds. Determine the displacement of Ben's car during this time period. Once more, the solution to this problem begins by the construction of an informative diagram of the physical situation. This is shown below...
In this article, we will learn how we can relate quantities like velocity, time, acceleration and displacement provided the acceleration remains constant. These relations are collectively known as the equation of motion. There are three equations of motion.

- Motion is the phenomenon in which an object changes its position.
- The first equation of motion is given as: v = u + at Where, v = final velocity u = initial velocity a = acceleration t = time taken
- The second equation of motion is given as: \(\begin{array}{l}S = ut + \frac 12~ at^2\end{array} \) Where, v = final velocity u = initial velocit...
- The third equation of motion is given as: \(\begin{array}{l}v^2 = u^2~ +~ 2as\end{array} \) Where, v = final velocity u = initial velocity a =...
- The area under the v – t graph represents the displacement of the body.
Apr 16, 2024 · Work is done when a force produces motion. (Example - To run, we require muscular force) Some distance shall be travelled in direction of force. Example - if we push a wall but wall does not move, so it is not work. But if we push a car and it moves in direction of force, it is work. Work = Force × Distance moved in particular direction.
