vectors & scalars
Questions here can ask you about any of the named vectors and scalars below. Learn the equations and know how to apply them. You can also get asked about vectors and scalars in general such as how can the same muscles be used to produce movement for the high jump take off and the sprint start?

impulse in sprinting
Questions here will only ask about Impulse in Sprinting. You must be able to identify the Force/Time graphs in relation to the three phases of a 100m sprint (Start, Middle, End- Accelerating, Constant Speed, Decelerating).
You may also be asked to draw a Force/Time graph. If this is the case you MUST label the graph correctly (X Axis Time Milliseconds /Y Axis Force Newtons) and you MUST make sure you draw the shape of the graph correctly ie negative first then positive for Acceleration.

newtons laws & application
Questions here will ask you to APPLY the laws to a sporting scenario.
For example ' Using Newton's Laws, explain how the performer is able to take off in high jump'. This means that you need to understand the law and not simply reel off the definition.
Common sporting scenarios are; Sprinter pushing out of the block, High Jumper pushing off the ground and a Tennis player moving towards the net.

projectile motion
Projectiles are anything that travel though the air.
Questions may ask you to label the vectors for a parabolic flight path- remember that air resistance is negligible and so the arrow remains the same length. The Gravity arrow will change in length throughout the flight path.
Questions have asked for you to name the three things that affect the distance a projectile travels.

angular motion
Questions here require you to apply the principles of Angular Momentum to a rotating body.
It will usually be an Ice Skater (Longitudinal Axis) or a Gymnast/ Diver (Transverse Axis). Either sporting example requires the same application. The body is nearer the axis of rotation the smaller moment of inertia and greater angular velocity = speeds up, the further away the body is from the axis of rotation the greater the moment of inertia and the smaller the angular velocity = slows down.
