P2: Resultant Forces Flashcards
What can force affect?
The shape of an object, its state of rest or its motion.
Newton
(N) the unit of force. (10N-1kg)
Resultant Force
The combined effect of the forces acting on an object.
When the resultant force acting on an object is zero…
It either remains stationary or Continues to move at a constant speed.
When the resultant force on an object is not zero…
The movement of an object depends on the size and direction of the resultant force.
The Parallelogram of forces
Used to fine the resultant force of two forces that do not act along the same line.
resultant force=
Mass x Acceleration
How can an object be accelerating but also moving at a constant speed?
If an object is moving at a constant speed, but always changing direction, then it has a velocity rather than a speed.
Formula for finding the Parallelogram of Forces
(sine of opposite angles)
