OCSCIENCE FINAL 2

QuestionAnswer
In a game of tug-of-war, you pull on a rope with a force of 100 N to the right and your friend pulls on the rope with a force of 100 N to the left. What is the net force on the rope? 0 NEWTONS
Something that starts, stops, slows down, or speeds up the motion of an object, and/or changes the direction of the object’s motion? FORCE
A force of 25N is required to move a box. If you wanted to increase the speed without changing force, what could you do to the mass? DECREASE MASS
If you want to make a surface less slippery, would you increase friction or decrease friction? INCREASE FRICTION
A student has two containers. Container A holds 1 liter of liquid. Container B holds two liters of liquid. Both containers are filled with same liquid. Are the densities of the two liquids equal or unequal? EQUAL
What is the density of a block of wood that has a mass of 12g and has a length of 1cm, a width 2 cm and a height of 3 cm? 2g/cm³
What are the three types of acceleration? Speeding up, slowing down and changing direction.
Why is there less gravity on the moon? It is smaller than Earth
What are the two factors that cause us to be in the Sun’s gravity field and not Pluto’s? Mass and Distance
If a question on the final gives you the speed and the distance and asks for what the time is, what equation do you use? distance = velocity x time
If a question on the final gives you the force and acceleration and asks for what the mass is, what equation do you use? Mass=Force/acceleration
If a question on the final gives you the mass and density and asks for what the volume is, what equation do you use? Volume=mass/density
What are the units for Force N
What are the units for acceleration? M/S/S
Weight on Earth is called what? gravity
The force of gravity depends on mass and distance
A person traveling in a car that stops suddenly keeps moving forward due to inertia and momentum

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
