Can anyone help me familiarize myself with the Kinematic Equations of Motion?
I need to know them for this summer institute.
Thanks,
Randeezy

The kinematic equations of motion are a set of equations used in physics to describe the motion of objects under the assumption of constant acceleration. They link displacement, velocity, acceleration, and time.
There are typically four main kinematic equations used to solve motion problems in physics when acceleration is constant.
Yes, the four kinematic equations are: 1. \( v = u + at \) 2. \( s = ut + \frac{1}{2}at^2 \) 3. \( v^2 = u^2 + 2as \) 4. \( s = \frac{u + v}{2} \times t \) Where \( v \) is final velocity, \( u \) is initial velocity, \( a \) is acceleration, \( s \) is displacement, and \( t \) is time.
Each equation is used depending on the known and unknown variables in a problem. For example, if initial velocity, acceleration, and time are known, and final velocity is unknown, you would use the first equation.
These equations are only applicable in scenarios where the acceleration is constant. They do not apply to situations where acceleration varies with time.
Yes, kinematic equations can be applied to vertical motion, such as the motion of a freely falling object, by taking gravity as the acceleration and considering the direction of motion.
Kinematic equations do not directly account for forces. They describe motion based on velocity, time, and acceleration, irrespective of the forces causing the acceleration.
