Physics I - Kinematics 🚙

What is kinematics

motion along a straight line

Explain displacement vs distance

Displacement is the distance between an object and its initial position - can be positive OR negative

Distance is the length of the path the object took to get to that position - is ALWAYS positive

Explain Scalars vs Vectors

Scalars are measured only numerically (ex. speed), while vectors are measured numerically AND by direction (ex. velocity).

What is the displacement formula

Displacement = Final position - Initial position

Explain the difference between speed and velocity

Speed just measures how fast something is going regardless of direction, always positive

Velocity measures speed and direction and can be positive or negative

How do you calculate average velocity?

Velocity = Displacement/Time

How do you calculate Average Speed?

Average Speed = total distance/total time
