A contact force is from
objects physically touching
far apart objects
not touching object
always a pull
A non-contact force is between
two objects that aren't touching
two objects that are touching
the ground and wheels
you and me
Gravity is a
Contact Force
Myth
Non-contact Force
Which is an example of a non-contact force?
elastic force
normal force
applied force
electric force
You are pulled to the surface of the earth due to the force of _________________
gravity
friction
normal force
contact force
Air Resistance Force
Contact Force
Non-Contact Force
What happens when a steel nail behaves like a magnet when it is touching a permanent magnet?
magnetism is induced
it becomes iron
nothing is attracted to it
it repels
What is the equation that links gravitational field strength, mass and weight?
weight = mass x gravitational field strength
weight = mass ÷ gravitational field strength
weight = gravitational field strength ÷ mass
What is the equation that links distance, force and work done?
work done = force x distance
work done = force ÷ distance
work done = distance ÷ force
What is the equation that links distance, time and velocity?
velocity = time x distance
velocity = distance ÷ time
velocity = time ÷ distance
What is the equation that links acceleration, change in velocity and time?
acceleration = change in velocity x time
acceleration = change in velocity ÷ time
acceleration = time ÷ change in velocity
What is the equation that links acceleration, mass, and resultant force?
resultant force = mass x acceleration
resultant force = mass ÷ acceleration
resultant force = acceleration ÷ mass
What is the resultant force in this diagram?
17 N, right
17 N, left
23 N, right
12 N, up

Joule (J)
What is the unit for force?
kilogram (kg)
meter (m)
Newton (N)
Joule (J)
What is the unit for energy?
kilogram (kg)
meter (m)
Newton (N)
Joule (J)
What is the formula for kinetic energy?
distance / time
mass x acceleration
velocity / time
½(mass) x (velocity)2
(mass) x (acceleration of gravity) x (height)
What is the formula for gravitational potential energy?
distance / time
mass x acceleration
velocity / time
½(mass) x (velocity)2
(mass) x (acceleration of gravity) x (height)
__________ energy is stored energy.
Potential
Kinetic
Force
Gravity
Gravitational potential energy depends on the ________ and ________ of the object.
Position (height) and mass
Friction and movement

Balanced
Unbalanced
Just after she jumps out of the plane (before the parachute opens). The relative forces will be
Weight force is equal to the friction force
Friction force is constant
Weight force is greater that the friction force
Friction force is greater than the weight force
Just after she jumps out of the plane (before the parachute opens). The net force will be
zero
upward
downward
Just after she jumps out of the plane (before the parachute opens). The sky diver will have
a constant speed
a constant acceleration
a constant velocity
After the 60 seconds, the parachutist pulls the cord and opens her parachute.
Explain how the parachute reduces the speed of the parachutist when it is just opened.
The friction force decreases
The weight force decreases
The weight force increases
The friction force increases
When a parachute canopy is opened more drag is created because:
