What is Newtons Third Law?

Which of the following is an external force?

• Friction

• Kicking a ball

Which best describes force absorption?

• Reducing force of impact between objects

• Action and reaction

• Using cushions

• Reducing time of impact

What is not a quantitative measure?

What is a force?

• Any interaction that, when unopposed, will change the motion of an object

• The resistance that one surface or object encounters when moving over another.

• The force that attracts a body towards the centre of the earth, or towards any other physical body having mass.

• A force that is caused by air. The force acts in the opposite direction to an object moving through the air.

What is an internal force?

• Structures of the body that interact to produce movement

• Result from the interaction between the body and the environment. These can include contact forces and non contact forces

• The ability or capacity to do something or act in a particular way

• The capacity or ability to direct or influence the behaviour of others or the course of events
