Physics A2

What is the viscous drag force?

Does opposing motion through fluid

What causes motion with uniform acceleration

A constant resultant force

Draw the free body diagrams for a table and the book it supports

How does trajectory change with fluid resistance

What is the normal force?

Force at right angles to surface of contact

State newtons 1st law

An object remains at rest or moving with constant velocity u less acted upon by a resultant external force

What is the tension force

Force opposing the stretching or squashing of a string or solid

How does velocity change with fluid reistance

How does time of flight change with fluid resistance

What is a free body diagram

One where all the forces on single isolated objects are shown

State newtons 3rd law

If body a exerts a force on body b, then body b will exert a force of the same type & magnitude but in opposite direction

What is the elastic restoring force

Force opposing the stretching or squashing of a spring

State newtons 2nd law

Force = rate of change of momentum and they are in the same direction
