Particles of air hinder the motion of an object (slow it down). So for instance, when someone skydives and parachutes out of a plane, gravity is pulling them down to earth, but air resistance (a type of friction) is also working in the opposite direction to slow them down. Air resistance is also known as drag in physics.
Children look at friction, how the force of air resistance affects moving objects, pushing and pulling and directions in which forces act. Each activity includes worksheets and teacher guidance.

19 Ιαν 2020 · The three practicals investigate: the relationship between the force needed to move a shoe over different types of surface. the relationship between surface area of a parachute and air resistance. do streamlined objects travel faster in water? What’s Covered. Friction is a force which opposes motion and is measured in newtons (N).
1 Οκτ 2024 · Friction is a force that works in opposition to the motion of an object. Frictional forces slow down the motion of the object. When friction occurs, energy is transferred by heating. Friction causes an increase in temperature of the object and its surroundings.
describe air resistance as a type of frictional force that slows down objects that move in air, identify that air resistance depends on the surface area, shape, and speed of an object, describe ways in which air resistance can be increased and decreased. Prerequisites. Students should already be familiar with.
