Science review

Review the following ideas and vocabulary for our upcoming science test.  Our test has been postponed for  Thursday, November 12th.

 

1.  Be able to  draw a picture of something MOVING.  Be able to label the FORCE that made it move (push or pull)

 

2.  Tell ways that a PUSH or PULL can CHANGE the way an object moves:

    -it can start an object moving

    -it can stop an object from moving

    -it can slow down a moving object

    -it can speed up a moving object

    -it can change the direction of a moving object

 

3.  How would you change the motion of a rolling ball to increase its speed?

    -push it with more force to make it go faster.

 

4.  What 3 things do we use to describe motion?

    -speed, direction, and distance

 

5.  An object at rest is __________________. (not moving at all)

      It will remain at rest until ______________. (a force (push or pull) acts on it.)

 

6.  What force makes objects fall to Earth?      (Gravity)

 

7.  If a book is at rest on a table, what forces are acting on it?

    -GRAVITY is trying to pull it down

    -The table is pushing up on the book

    -Because these are EQUAL forces the book will not move.

 

8.  What would be a way to get a book moving that is at rest on a table?

    -push it off

    -pull it off with your hands

    -remove the table, then the force of gravity will pull it down

 

 

10.  What are 2 forces that start an object in motion?     (Push and pull)

 

11.  What are 2 forces that stop or slow down an object in motion?  (Gravity and Friction)
