• Curvilinear motion

• Linear motion

• Rotational motion

• Circular motion

What is the term used to describe the rotation or turning about an axis?

What determines the type of motion that an object or body will undergo when a force is applied?

• Point of application of the force

• Magnitude of the force

• Direction of the force

• Type of object or body

What type of force always results in rotational motion?
