What is the best way to remember the four kinematic equations and what they mean and when you apply them?
Thank you.
Thank you.

Thank you.
The four kinematic equations are a set of mathematical equations that describe the relationship between an object's initial velocity, final velocity, acceleration, displacement, and time. They are commonly used to solve problems related to motion.
To use the four kinematic equations, you must first identify which variables are known and which are unknown. Then, select the appropriate equation to solve for the unknown variable. It is important to pay attention to units and use the correct units when plugging in values to the equations.
The units for the four kinematic equations are:
- Velocity (v) in meters per second (m/s)
- Initial velocity (u) in meters per second (m/s)
- Acceleration (a) in meters per second squared (m/s^2)
- Displacement (s) in meters (m)
- Time (t) in seconds (s)
Average velocity is the total displacement divided by the total time, while instantaneous velocity is the velocity at a specific moment in time. Average velocity gives an overall picture of an object's motion, while instantaneous velocity gives more specific information at a particular time.
- The equations only apply to objects moving with constant acceleration
- The equations are only valid in one dimension (x, y, or z)
- Make sure to use the correct units
- Be consistent with the direction of positive and negative values
- Double check that your answer makes sense in the given scenario
