Types of Forces Flashcards
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 (objects touching)
2. Non-contact forces (objects separated)
Give three examples of contact forces.
- Friction
- Air resistance
- Tension
Give three examples of non-contact forces.
- Gravitational forces
- Electrostatic forces
- Magnetic forces
Is force a vector or a scalar quantity? Why?
● Vector
● It has both magnitude and direction
What is a scalar quantity?
● Aquantity that only has a magnitude
● Aquantity that isn’t direction
dependent
What is a vector quantity?
Aquantity that has both magnitude and
direction
Give three examples of vector quantities
- Velocity
- Displacement
- Force
Give examples of scalar quantities
● Temperature ● Time ● Mass ● Speed ● Distance ● Energy
What magnitude would the resultant force have and
in what direction would it be pointing?

How are vectors represented?
● Vector arrows
● Length indicates magnitude
● Arrow indicates direction
How can you calculate the resultant magnitude and
direction of forces using a scale drawing?
● Draw the component forces as scaled arrows, joined tip-to-tail
● Draw a line connecting the two open ends.
● Measure the length of this line and convert into the magnitude.
● Measure the angle between the resultant line and the
vertical/horizontal to find the direction
