Transcript of FORCES IN ACTION

Forces in Action
Can you answer the following?
What is a force?
What are some common examples of forces?
What effet do contact and non-contact forces cause?
How do we show forces in diagrams?
How do we measure forces in an experiment?
Important vocabulary
Gravity, magnetism, electrostatic
Friction, air resistance, buoyancy, surface tension
Mass and weight
Terminal velocity
Newton's three laws of motion

Important concepts
A force is a push or a pull
There are contact and non-contact forces
Forces have direction and magnitude
Forces can cause an object to:
start/stop motion
change direction
change shape
Forces are measured in Newtons (N)

Important experiments
There is more than one force acting on falling objects -
air resistance
(N) is different from
Magnets can attract and repel
can affect the fall of a parachute
can be friend and foe
Things are lighter in water due to
which differs from
surface tension
