Kinematic Equations Mechanisms such as robot manipulators are defined through mechanical equations that relate movement at one or more joints to their configuration. A joint is responsible for configuring the device for a particular task position.

What are the Kinematic Equations?

kinematic equation

Kinematic equations describe objects traveling with constant acceleration. Integrals, derivatives, and rates of change are all necessary for solving kinematic equations. Integrals will not be covered because high school physics is the focus of this course. 5 kinematic equations

What Exactly Kinematic :

Kinematic deals with the motion of objects in classical mechanics in Physics. It consists of looking at movement without referencing the force causing it.

Object motion is known as kinematic, a concept that includes speed or velocity, distance or displacement, and acceleration, whose values vary with time.

In introductory physics classes, kinematic is usually the first module because it’s such an everyday subject. If you’ve ever thrown anything into the air, then you already know something about kinematic!

Physicists aren’t required to know much about kinematic, so they’ll get by with just a basic understanding. As a result, kinematic is the topic of physics that is most relevant to everyday life.

Getting a handle on it can be a helpful first step toward understanding more advanced physics topics. In the following guide, the most important terms are highlighted in bold. You can use that definition to come up with your examples to explain it.

Which kinematic formula should you use?

If we have a known unknown and three variables that we already know, then we should choose a kinematic formula that includes both variables. Therefore, we obtain the solution for the formula’s one unknown.

Displacement, Acceleration, Velocity, and Air Resistance:

When we use the kinematic equations, some mathematical assumptions can be made. A moving object’s velocity is slowed by air resistance when it passes through the air.

We assume that air resistance is too small to consider when using the equations of motion. There are so many kinematic equations calculators are available on the Internet.


Distance and direction of displacement are measures of motion. The unit of measure is usually metered (m). In many cases, removal and distance are confused. There should be a distance and a direction associated with the displacement.

In other words, an eviction will be a distance greater than “5”, but just “5” won’t.

Acceleration :

When velocity changes over time, it is said to be accelerating,

The magnitude of change and its direction is measured by acceleration, just like the two preceding terms. A meter per second squared (m/s2) is its standard unit. Despite a constant velocity for an object, if the direction of the object changes, there could be an acceleration.


Velocity is the rate at which a position moves over a given period; it measures how fast and how quickly it moves. Metric speed (m/s) is its standard unit. Velocity and speed are often confused with one another, just as displacement and distance are.

In this case, a director needs to be specified for velocity.

With the above equation, velocity is usually calculated as the average velocity representing all speeds calculated for a specific period. It can take seconds or milliseconds for the period to pass.

Unlike instantaneous velocity, instantaneous velocity can only be measured at a specific point in time. Using derivatives and integrals, one can calculate quick rates.

Since calculus does not appear on the MCAT, the instantaneous velocity is excluded from the test. In any case, you might be asked to compute the average speed using a table of values.

Air Resistance:

A force opposing an object’s relative motion in the air is referred to as air resistance. Drag forces slow down an object when acting counter to the oncoming flow velocity.

Unlike other resistance forces, drip depends directly on speed due to its opposite direction of action relative to the movement.

The top surface of an object collides with air molecules to create air resistance. Therefore, the two most common factors determining how much air resistance an object will experience are its speed and cross-sectional area.

Air resistance will increase with both increased rate and cross-section area.

Approaches to solving problems:

  1. Describe the physical situation using a diagram.
  2. The given information should be listed in variable form.
  3. List the variables for the unknown information.
  4. Determine from general information the anonymous information that will be used to determine the unknown knowledge.
  5. You must substitute known data into the equation and follow appropriate algebraic steps to solve the unknown information.
  6. Check the answer to sure it is logical and mathematically correct.
