What is Kinematics?

Kinematics is a part of physics. It looks at how things move without worrying about what makes them move.

It talks about three main ideas:

1. Displacement: This is how much the position of an object changes. We usually measure it in meters (m).

2. Velocity: This is about how fast something is moving. It's the change in displacement over time, which means how far something goes in a certain amount of time. We can write it like this:
   ( v = \frac{d}{t} )
   Here, ( d ) is the distance traveled, and ( t ) is the time taken. Velocity is measured in meters per second (m/s).

3. Acceleration: This is how quickly something speeds up or slows down. To find acceleration, we can use this formula:
   ( a = \frac{v_f - v_i}{t} )
   In this formula, ( v_f ) is the final speed, ( v_i ) is the starting speed, and ( t ) is the time taken. Acceleration is measured in meters per second squared (m/s²).

Knowing about kinematics helps us figure out where an object will be in the future. This is really important for jobs like engineering and robotics.
