Forces Flashcards
What is a scalar quantity?
A quantity that only has a magnitude
What is a vector quantity?
A quantity that has both a magnitude and a direction
Examples of vector
Velocity
Displacement
Force
Examples of scalar quantities
Time
Mass
Speed
Distance
What is a force?
A push or pull acting on an object due to an interaction with another object.
What are the two categories that all forces can be split into?
Contact forces
Non-contact forces
Examples of contact forces
Friction
Air resistance
Tension
Examples of non-contact forces
Gravitational forces
Electrostatic forces
Magnetic forces
Is force a vector or a scalar quantity?
Vector
It has both a magnitude and an
associated direction
What is weight?
The force that acts on an object due to gravity and the object’s mass
What is meant by an object’s center of mass?
The single point where an object’s weight can be considered to act through
What is the resultant force?
The overall force acting on an object
The equation for work done
Work done = Force x Distance
