forces

Question 1

hooke’s law

Answer 1

states that the extension x is directly proportional to the force F applied on the spring or wire provided the limit of proportionality is not exceeded

Question 2

hooke’s law

Answer 2

states that the extension x is directly proportional to the force F applied on the spring or wire provided the limit of proportionality is not exceeded

Question 3

upthrust

Answer 3

is the resultant vertical upward force exerted by the surrounding fluid on a fully or partially submerged body as the pressure on the bottom surface is greater than that at the top

Question 4

upthrust

Answer 4

is the resultant vertical upward force exerted by the surrounding fluid on a fully or partially submerged body as the pressure on the bottom surface is greater than that at the top

Question 5

pressure (definition)

Answer 5

normal force F acting per cross-sectional area A

Question 6

archimedes principle

Answer 6

states that when an object is wholly or partially immersed in the fluid, it is buoyed by an upthrust equal in magnitude and opposite in direction to the weight of the fluid displaced by the body
