Application of Forces

Define Gravity:

• Is equal when a constant speed is maintained

• The force that attracts the body towards the centre of the Earth

• An equal force that pushes against muscular force applied to the ground

• The opposing force applied to an accelerating body

Define Muscular Force:

• an equal and opposite reaction the body exerts on the ground

• a frictional force that air applies to a moving object

• a constant force applied by sprinters

• a push or pull applied to an object provided by muscular contraction

....... is the frictional force that air applies to a moving object.

The statement: "it is an equal and opposite reaction to the force that the body exerts on the ground" refers to....

• Gravity

• Ground Reaction

• Muscular Force

• Air Resistance

"Pulls a performer or projectiles downwards and towards the ground"

The statement refers to:

• Pulling Force

• Gravity

• Air Resistance

• Ground Reaction

................. occurs when muscular force exceeds air resistance.

...................... will be maintained when opposing forces are equal.

..................... occurs when air resistance exceeds muscular force.

Draw an arrow that indicates the air resistance action on the performer.

Indicate at which moment "ground reaction" acts on this performer.
