Forces And Their Effects Flashcards
1
Q
Moment =
A
Force x distance perpendicular to the direction of the force
2
Q
What Is the principle of moments in situations where rotational forces are in equilibrium
A
Sum of clockwise moments = sum of anticlockwise moments
3
Q
 Does increasing the distance to the pivot require more force or less force to open a door explain why
A
Less force required as it creates a large moment due to the large distance 
4
Q
How can you reduce unwanted energy transfer eg. Friction releasing heat 
A
Lubrication
