Term1/13

Which law states that the total momentum does not change when it is transferred

Definition1/13

The law of conservation states that the total momentum does not change when it is transferred.

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

What most influences whether or not an object will float

Definition1/13

An object's density influences its buoyancy, thus determining whether or not an object will float

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

How is sound energy produced and transmitted

Definition1/13

by vibration of particles and fluids.

Term1/13

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

Definition1/13

height and mass

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

What best describes thermal energy

Definition1/13

energy of molecular motion

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 infroemation is needed to calculate the amount of energy needed to heat a volume of water to some temperature

Definition1/13

You need to know the amount of water (mass), how many degrees you want to heat it up, and the specific heat of water. Then - if everything is in compatible units - you must simply multiply the three together.

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".
