Biomechanics - Force

What is Newton's First Law of Motion?

• an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• When a force acts on an object, the motion experienced by the object is proportional to the size of the force and in the direction in which it is applied.

• For every action, there is an equal and opposite reaction.

The amount of matter that makes up an object

• Mass

• Inertia

• Measures the rate (speed) of the positional change of the object

How quickly an object can change velocity when an unbalanced force causes movement.

• Mass

• Acceleration

• Elasticity
