What is force?
A force is best described as a push or a...
pull
This force stops objects from sliding past each other
friction
when forces are balanced, an object will ...... or move at a constant speed
stay still
The unit force is measured in
Newtons (N)
The ... of a practical explains what you are trying to find out
the aim
What force pulls objects toward the earth?
gravity
friction
students pulling on a rope 50N to the left and 15 to the right, resulting in a net force in which direction
35N to the left
The tool used to measure force
force meter
A predication written before an experiment is called a
hypothesis
Name one effect a force can have on an object
change shape/speed/direction/start-stop movement
force that is acting upwards on a book on a table
normal force
if two forces are equal in size and opposite in direction they are considered
balanced
The variable you change in an experiment
independent
This section lists equipment and steps
method
A force that slows objects moving through the air is called
air resistance/drag
The force that supports a boat in water
buoyant force
90N to the right, 42N to the left which was is the ball moving and by how many N
38 to the right
the variable you measure in an experiment
dependent
This is how you would organise raw data
tables
gravity/normal force
Name two contact forces
friction/air resistance/applied force/normal force
speeds up/slows down/changes direction
The variable you cannot keep the same during an experiment
uncontrolled variable
a conclusion should state whether the....... was supported or not
