Balance and stability

Question 1

Equilibrium meaning?

Answer 1

no unbalanced forced acting on it, an object in equilibrium is either motionless or moving with constant velocity.

Question 2

Stability meaning?

Answer 2

the resistance to the disruption of equilibrium.

Question 3

Balance meaning?

Answer 3

ability to control equilibrium

Question 4

Static equilibrium meaning?

Answer 4

the state in which the body has zero velocity and zero acceleration. Sum of all forces and movement are zero

Question 5

Dynamic equilibrium meaning?

Answer 5

the body or object is moving with constant velocity, no change in speed or direction.

Question 6

Base of support to maintain equilibrium?

Answer 6

larger the base of support, greater stability
smaller the base of support, lesser stability

Question 7

Centre of gravity to maintain equilibrium?

Answer 7

lower centre of gravity, greater stability
higher centre of gravity, lower stability

Question 8

Body mass to maintain equilibrium?

Answer 8

heavier body mass, harder to move
lighter body mass, easier to move

Question 9

Friction to main equilibrium

Answer 9

increase friction, increased satbility
decrease friction, decreases stability
