SCIENCE UNIT 2 CH 1

QuestionAnswer
VOCAB: An event or process that leads to a result or change Cause
VOCAB: A result or change that happens because of an event or process Effect
VOCAB: Speed in a particular direction Velocity
VOCAB: A push or pull that can change the motion of an object Force
VOCAB: To apply a force Exert
VOCAB: A force between an object and the surface it is moving over Friction
VOCAB: The energy that an object has because it is moving Kinetic Energy
VOCAB: The energy that an object has because of its place or position Potential Energy
VOCAB: To reach a conclusion using evidence and reasoning Infer
What are the five ways an object's velocity can change? 1. Start Moving 2. Speed Up 3. Slow Down 4. Stop 5. Change Direction
Start Moving=________________________ Push the object in any direction
Speed Up=________________________ Push the object in the same direction
Slow Down=________________________ Push the object in the opposite direction
Stop=________________________ Push the object in the opposite direction
Change Direction=________________________ Push the object in the opposite direction
The stronger the force acting upon an object, the stronger the change in _______________________ of that object. velocity
An object sliding across the a carpet slows down quicker than bare floor, because the carpet exerts more ________________________________. friction
Think back to our space pod. The thrusters fire to exert a force in the ___________________________ as the motion of the pod, causing it to stop. opposite direction
Think back to our space pod. If the thrusters fired and caused the pod to move in the opposite direction, the thrusters exerted a _____________________ force than in other missions. stronger
Think back to our space pod. If the thrusters fired and caused the pod to crash into the space station, the thrusters exerted a ________________________ force than in other missions. weaker
Claim 1 States, “The thrusters on the pod caused the pod to move in the opposite direction.” Using force, velocity, exert, and cause, explain! The thrusters on the pod exerted more force than in usual pod missions. This caused the velocity of the pod to change direction.
Claim 2 States, “The thrusters only slowed the pod, it didn’t stop; the pod hit the space station, which made it bounce and move in the opposite direction.” Using force, velocity, exert, and cause explain! The thrusters on the pod exerted less force than in usual pod missions. This caused the velocity of the pod it slow down and bounce off the space station.

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.
