Forces and Motion Flashcards
1
Q
Contact Force
A
something like air resistance, involves contact
2
Q
Elastic Limit
A
point where object has stressed more than expected and can no longer return to its normal shape
3
Q
Equilibrium
A
when forces have no overall turning effect, meaning the resultant force is often zero
4
Q
Hooke’s Law
A
states that the extension of a spring is directly proportionate to the force applied, provided its limit of proportionality is not extended
5
Q
Non-Contact Force
A
something like gravity, that does not require contact
6
Q
Parallelogram of Forces
A
used to work out resultant forces when forces don’t just go up and down
7
Q
Resultant Force
A
the net force acting, the sum of all forces acting on the object
