Key Topics to Revise

Vectors and Scalars

Scalar quantities have only magnitude (mass, temperature, speed, energy)
Vector quantities have both magnitude and direction (displacement, velocity, acceleration, force)
Vectors are represented by arrows with length showing magnitude and arrow showing direction

Projectile Motion

Motion of object thrown at angle with horizontal under gravity only
Two independent motions: uniform horizontal motion and uniformly accelerated vertical motion
Horizontal velocity remains constant: vx = u cos θ

Circular Motion

Motion along circular path with constant speed is uniform circular motion
Speed is constant but velocity changes due to changing direction
Acceleration is always directed toward center (centripetal acceleration)
