wheight
Give the name of the TWO forces represented by the arrows
air resistance (upwards) and weight (downwards)
Look at the diagram, what are the directions (arrow) of the pushing and friction forces ?
friction (left) and push (right)
Look at the diagram, what are the directions (arrow) of the contact force and weight?
weight (downwards) and contact force (upwards)
The drawings shows a book hanging from a forcemeter. What is the weight of the book ?give the value and the unit
8 Newtons (8 N)
what does streamlined mean ?
streamlined describes the shape of an object that has a low air resistance.
when two forces cancel each other we say that they are...
Balanced
