has both magnitude and direction
Give an example of vector quantity. - correct-answers-force,
velocity, displacement, acceleration, momentum
What is a contact force? - correct-answers-When two objects
have to be touching for a force to act
What is an example of a contact force? - correct-answers-
friction, air resistance, tension in ropes, normal contact force

do not need to be touching for a force to act
Give an example of a non-contact force - correct-answers-
Magnetic force, gravitational force, electrostatic force
What is gravity? - correct-answers-a force of attraction
between objects due to their masses
What is mass? - correct-answers-the amount of matter in an
object
What is weight? - correct-answers-the force of gravity on an
object
Gravitational strength varies depending on..... - correct-
answers-location
Mass and weight are... - correct-answers-directly proportional

showing all the forces acting on an object
, What is a resultant force? - correct-answers-The overall force
on a point or object
If a resultant force moves an object..... - correct-answers-work
is done
When a force moves an object through a distance, what
happens? - correct-answers-energy is transferred and work is
done on an object
One joule of work is done when a force of one newton causes
an object to move how many meters? - correct-answers-One
meter
What is work done measured in? - correct-answers-Joules (J)
What is force measured in? - correct-answers-Newtons (N)

answers-balanced
What does stretching, compressing or bending transfer? -
correct-answers-Energy
What does elastically deformed mean? - correct-answers-When
an object can go back to its original shape and length after the
force being used to stretch (or compress) it has been removed
What does inelastically deformed mean? - correct-answers-An
object that doesn't return to its original shape and length after
the force has been removed
Extension is directly proportional to what? - correct-answers-
Force
There is a limit to the amount of force you can apply to an
object for the extension to keep on increasing what? - correct-
answers-Proportionality
What is a fluid? - correct-answers-A substance that flows
freely, such as a liquid or a gas
