Momentum
Momentum is the measure of an object’s motion and is calculated by multiplying the object’s mass by its velocity. -
What are momentum and impulse?
Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. -
Mass, Inertia, and Momentum
Inertia is the reluctance of a body to change whether it is moving or not and is related to its mass.

What is the difference between laminar flow and turbulent flow?
Article explaining the difference between laminar and turbulent flows.

Pressure drag
Image attached.
Pressure drag is caused by the air particles being more compressed (pushed together) on the front-facing surfaces and more spaced out on the back surfaces. -
Pressure drag
Air flowing past an object pushes harder against the front than the back. This difference creates a backward force called pressure drag.

Pressure drag
A range of articles and videos on pressure drag in sport.

Chapter 10: Fluid Mechanics
Chapter outlines various types of drag, Bernoulli's Principle, and fluid mechanics.

Of Racing Suits And Aerodynamics
In many sports that involve high-speed movements, drag or air resistance is probably one of their biggest enemies in achieving their peak performance. -
Air Resistance and Drag
Air resistance, drag, and fluid resistance mean the same thing.
-
‘Fast suits’ and Olympic swimming: a tale of reduced drag and broken records
In the water, invisible forces slow the swimmer down. These fluid forces - called drag - push against your swimming motion.

How to Reduce the Three Types of Frontal Drag
Swimmers are constantly looking for new and innovative ways to swim faster and more effectively.

Surfboard Fin Science
Fins do two things, and only two things, in terms of science. A fin creates two forces–and two forces only.
Surfboard fins create lift and fins create drag.

Bernoulli Principle
The Bernoulli principle explains why aeroplanes fly and racing cars stick to the ground going around corners when they really shouldn’t.

Sprinting, jumping and the laws of physics: welcome to discuss
Scientists use such terms as "symmetric airfoil", the "Bernoulli principle", "wind velocity" and "frictional force" to explain the phenomenon.

How Does a Curveball Curve?
The same principles that allow curveballs to curve also allow airplanes to fly. This is demonstrated by something called Bernoulli's principle

Spin & The Magnus Effect
Spin is created by applying a force that is off centre to the object being thrown (or kicked) at the point of release.

Setting the Curve: The Magnus Effect and its Applications
Magnus Effect in Sports
If you’ve ever seen a soccer player bend a shot around a wall of players or a baseball pitcher throw a curveball, then you’ve seen the Magnus effect at work.
