Cards in this guide (10)
Force can be calculated as pressure x area Which of the following will produce the most force
Speed is calculated by distance over what other factor
A car travels 65 km in 1 hour What is its average speed in meters per second
Resultant velocity is calculated using which two math functions
"addition and subtraction"
Resultant velocity refers to the sum of all vectors in an equation. The two math functions that are used to calculate the resultant velocity are addition and subtraction.
What if your body applies force to the ground as weight If you weigh 450 newtons and carry a backpack that weighs 45 newtons what is the net force applied downward to the ground
What does the law of conservation of energy explain
The total energy in the universe is constant.
A+ :)
What creates the lift that allows gliders to fly
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.
What will happen if too much tension force is exerted on a spring
The popping sensation a person feels in his or her ears when an airplane ascends or descends comes from the rapid change in what type of pressure
Which type of force is exerted on the bottom row of bricks in a building
