Term1/13

A desk weighs 500 N with gravity applying that force downward If you apply 275 N upward force and a friend helping you applies 275 N upward force what is the net force applied

Definition1/13

50 N upward

Term1/13

Which type of force is exerted on the support ropes of a hammock when you lie in it

Definition1/13

Tension

Term1/13

What creates the lift that allows gliders to fly

Definition1/13

Unequal Pressure

The aircraft's wing is shaped so that the air passing over the wing moves faster than the air under the wing causing a positive pressure differential, thus creating lift. In simpler terms, it is the air moving above the wing, not below the wing, that causes lift.

Term1/13

What term describes an energy resource that can be used up

Definition1/13

nonrenewable energy

Term1/13

Which factors must be known to calculate an object's gravitational potential energy

Definition1/13

height and mass

Term1/13

Which of these would you expect to produce the most centrifugal force A spinning arms slowly B spinning forearms arms slowly with biceps tightly at sides C swinging arms fast in circles with arms out

Definition1/13

swinging your arms around in circles very quickly

Term1/13

A speed boat is moving at a velocity of 25 ms runs out of gas and drifts to a stop 3 minutes later 100 meters away What is the rate of deceleration

Definition1/13

0.14

Term1/13

Which force allows hot air balloons to fly

Definition1/13

Buoyancy allows hot air balloons to fly.

Term1/13

Which fundamental force contributes to pressure in both water and the atmosphere

Definition1/13

gravity

Term1/13

What is the method used to produce nuclear energy in power plants

Definition1/13

nuclear fission

Term1/13

Which of these is a type of drag force turbulence tension thrust and compression

Definition1/13

turbulence

Term1/13

What following objects has the greatest density in grams

Definition1/13

50 gram object that is 25 cm

Term1/13

What is the si unit for pressure which is equal to 1 n exerted over 1m 2

Definition1/13

That unit has the special name "pascal".
