How do I know what formula to use?? I'm getting confused.

You write down the variable you want to know and the variables you have been given. You choose the formula which contains just those variables (and no others) and re-arrange it to get what you want.Jacqueline71 said:How do I know what formula to use??

Chandra Prayaga said:First, look at the definition of power:
Kinematics is the branch of physics that studies the motion of objects without considering the forces that cause the motion. It describes the position, velocity, and acceleration of an object as it moves through space.
2.Some common kinematics formulas include:
- Displacement (Δx) = Final position (xf) - Initial position (xi)
- Average velocity (v) = Δx/Δt
- Average acceleration (a) = Δv/Δt
- Final velocity (vf) = vi + at
- Displacement (Δx) = vit + ½at^2
To solve a kinematics problem, you will typically be given some information about the motion of an object, such as its initial position, velocity, and/or acceleration, and asked to find a missing variable. You can use the appropriate kinematics formula, plug in the given values, and solve for the missing variable. It is also important to pay attention to the units of measurement and use the appropriate formula for the given situation.
4.Speed is a measure of how fast an object is moving, while velocity is a measure of how fast an object is moving in a specific direction. In other words, velocity takes into account both the speed and direction of an object's motion, while speed only considers the magnitude of the motion.
5.Kinematics is closely related to other branches of physics, such as dynamics and mechanics, as it provides a foundation for understanding the motion of objects. Kinematics can also be applied to other fields of science, such as engineering and astronomy, to analyze and predict the motion of objects in various systems and environments.
