what is a force
A push or pull that acts on an object due to the interaction with another object
what can applying a force to an object cause the object to do
stretch, compress or bend
are forces scalar or vector quantities
vector as they have both a magnitude and direction
what is force measured in
newtons (N)
the strength of a non contact force _____ as the objects get further apart
decreases
what is electrostatic force
The force between charged objects can be attractive or repulsive
what is gravity
the force of attraction between any two objects that have mass
what are contact forces
Forces that act when two objects are physically touching
what is upthrust
the supporting force exerted by a fluid on an object acting upwards
what is air resistance
a resistive force attempting to slow an object due to rubbing pm a surface or against air opposing the motion
what is tension
the pulling force being exterted through a rope
give an example of normal contact force/ reaction force
a rock on a table has mass so it exerts the force of weight downwards, to keep it in place and stop it from falling the table must be exerting an equal and opposite force upwards
