3. Equilibrium Flashcards
when does equilibrium exist
when mass moves with constant velocity or is at rest
what are the net forces on a system in equilibrium
0
what is the relationship between the sum of magnitudes of the downward and upward forces in equilibrium
both are equal
what are the 2 types of motion
both are equal
what is the relationship between the sum of magnitudes of the leftward and rightward forces in equilibrium
translational - straight
rotation - rotating
when an object experiences a force what happens - 3 things that can happen
either undergo translational/rotation or combination of both forces
what does rotational motion deal with
rotation of a body about its axis
what causes rotation of an object around the axis
perpendicular forces = torque
what is the equation for torque
T = F x L
is clockwise and anticlockwise negative or positive
clockwise = negative
anticlockwise = positive
what two things add together to determine the net torque
clockwise and anticlockwise torques
