Key Stage 3
Meaning
Drag is a force that acts to decelerate objects that are moving in a fluid.
About Drag
- Drag is a force so it is measured in Newtons.
- Drag is a contact force because an object must be in a fluid for drag to exist.
- When an object is moving through the air drag is called air resistance.
- When an object is moving through the water drag is called water resistance.
- Drag can be reduced by making an object more 'streamlined'.
Key Stage 4
Meaning
Drag is a force that acts to decelerate objects that are moving in a fluid.
About Drag
- Drag is a force so it is measured in Newtons.
- Drag is a contact force because an object must be in a fluid for drag to exist.
- When an object is moving through the air drag is called air resistance.
- When an object is moving through the water drag is called water resistance.
- Drag can be reduced by making an object more 'streamlined'.
- Drag exists because objects moving through a fluid collide with particles in that fluid passing on some of its momentum which causes the object to lose momentum and therefore slow down.

Key Stage 5
Meaning
Drag is the force of fluid resistance on an object moving through the fluid.
About Drag Force
- Drag is also known as air resistance or fluid resistance.
- Drag opposes the motion of the object and acts in the direction opposite to the velocity.
- Drag depends on the velocity of the object, the viscosity of the fluid, and the shape and surface area of the object.
