Aqa Physics P8 (Triple) Flashcards
Distance in a given direction
Displacement is...
A straight line between two points
Displacement is measured as
Magnitude only
A Scalar Quantity has
Magnitude and Direction
A Vector Quantity has
more than one force acting on an object
A Scale diagram is used to show
Newtons
Force is measured in
Newton's Third Law
"When two objects interact with each other they exert equal and opposite forces on each other" Which Law is this
Contact
Friction is what type of force?
Newton's First Law
" If the forces acting on an object are balanced, the resultant force on the object is zero" Is which Law?
Accelerating
If the forces acting on an object are unbalanced the object must be...
Resultant Force
Free-Body diagrams are used to find
A single force that describes the overall effect on an object
Resultant Force can be described as
The Turning effect of a force
A Moment is
Increasing the force or increasing the distance the force is applied from the pivot
Moments can be increased by..
F x d
M =
Nm
Units for M are
Multiply Forces
Gears are used to...
a Low speed and a High turning effect
A Low gear gives...
High speed and a Low turning effect
A High gear gives a...
The point at which the majority of the mass is located.
The Centre of mass of an object is...
Finding the point where the lines of symmetry intersect
A Symmetrical object's centre of mass can be found by...
The Clockwise and Anticlockwise Moments must be equal
For an object that is not turning
The Parallelogram of forces
The Geometric method for finding the result force of non-opposite forces is
A Protractor
What piece of equipment must you have when using the parallelogram of forces
Equilibrium
An object at rest is in...
