Biomechanics- Chapter 3

Force is defined as....

• Force of attraction between two objects

• Moving with constant Velocity

• A push or pull acting on an object

• The amount of matter an object is made up of

On earth, gravitational force causes objects to fall. Acceleration due to gravity is

• 9.8m/s2

• 8.9m/s2

• 10.1m/s2

• 7.9 m/s2

Mass is defined as

• The amount of matter an object is made up of

• A measurement tool when two surfaces meet

• Forces acting on the body

• Is a product of gravity weight

Weight =

• Gravity x Weight

• Mass x Gravity

• Inertia x Mass

• Mass x Accleration

A frictional force that occurs when one of the surfaces is air or water is known as

• Angular force

• Frictional Fore

• Force

• Drag Force

An object’s resistance to change its state of motion is referred to as

• Impulse

• Inertia

• Resistance

• Mass

Momentum is a measure of the amount of motion an object has and its resistance to changing that motion. The formula for momentum is

• P=MA

• M=MV

• P=MV

• M=PV

Conservation of momentum is

• The total momentum before the collision doubles afterwards

• The total momentum before the collision equals total momentum after collision

• Total momentum after the collision is halved

• Momentum at constant velocity of 9.8m/s

The Sequential and co-ordinated movement of each body segment to produce maximal velocity is known as

• Conservation of velocity

• Summation of velocity

• Conservation of momentum

• Summation of momentum

The formula for impulse is

• Impulse= Speed x Force

• Impulse= Mass x Time

• Impulse = Force x Time

• Impulse = Force + Time
