Biomechanics 4.3.1-4.3.5

What is the definition of the term impulse?

• The rate of change of velocity

• A force that acts in opposite to the movement of one surface on another

• The product of force multiplied by the time during which the force acts

• The speed of an object in a given direction

What is displacement?

• The speed of an object in a certain direction

• The amount of motion possessed by a moving body

• The rate of change in velocity

• The shortest distance from the initial to the final position of a moving body

A measurement that has only size (or magnitude).

• Scalar

• Vector

A measurement that has both size and direction.

• Scalar

• Vector

Select ALL the vector quantities.

• Acceleration

• Velocity

• Distance

• Speed

This term describes "how far an object or body travels"

• Time

• Displacement

• Velocity

• Distance

 A change in displacement over time is known as..(hint: vector quantity)

• Speed

• Acceleration

• Momentum

• Velocity

A change in velocity divided by the time taken for the change to take place.  It has size and direction so is a vector.

• Distance

• Velocity

• Acceleration

• Impulse

What is momentum?

• The application of force over a period of time

• The amount of motion possessed by a moving body (mass x velocity)

• The rate of change in velocity

• I don't know :(

A force.. Select all the correct definitions

• Is a push or a pull.

• Is a scalar quantity.

• Is measured in kilograms.

• Is a vector quantity.
