7/2 Understanding Types of Forces

Concurrent force is a term used to describe forces that:

• act at the same point

• act in the same direction

• have the same magnitude

• occur at the same time

Explain what is meant by 'non-concurrent force'.

• A force that acts at a single point

• A force that does not act at a single point

• A force that is always in equilibrium

• A force that acts in a circular motion

Explain what is meant by 'coplanar force'.

• A force that acts in three dimensions

• A force that acts in a single plane

• A force that acts in a vacuum

• A force that acts in a circular motion

'Non-contact force' is a force that:

• acts only when objects are in physical contact

• acts at a distance without physical contact

• requires a medium to travel through

• is always attractive in nature

A ______ (F) is a push or a pull that acts on an object due to interaction with another object. Force is measured in newtons (N).

• Force

• Energy

• Mass

• Velocity

______ is expressed as the amount of work done by a force.

• Energy

• Power

• Force

• Velocity

______ is defined as the amount of energy transferred per second, measured in watts (W).

• Power

• Energy

• Force

• Work

A system of forces is:

• a single force acting on a body

• multiple forces acting on a body

• a force that does not cause motion

• a force that acts in a vacuum

What type of force is described as not involving physical contact?

• Non-contact

• Concurrent

• Non-concurrent

• Coplanar

Which type of force involves forces that meet at a common point?

• Non-contact

• Concurrent
