What is velocity?

100

Name a difference between weight and mass.
What is weight is how heavy something is and mass is how much space it takes up.

200

The change of position during a unit of time is called__________________.
What is speed?

200

A change in speed or direction of an object's motion ______________________________. This change could be that we speed up, slow down, or turn.
What is acceleration?

200

_________________ is the measurement of the force of gravity on an object.
What is weight?

200

It is field day and our class is participating in the tug-of-war. If both sides are pulling with the same force and the rope doesn't move, we call that _______________________.
What is balanced forces?

200

Is every object on the Earth moving? Why or Why not?
What is yes. The Earth is revolving around the sun, and rotating on its axis.

300

The speed and direction of an object.
What is velocity?

300

The property of matter that keeps a moving object moving in a straight line.
What is inertia?

300

The term___________________ describes how hard it is to slow down or stop an object. The formula for finding it is mass X velocity.
What is momentum?

300

We continue the tug-of-war and we begin to win; the rope is pulled towards or side! The forces are now: _______________________.
What is unbalanced?

__________________ is the location of an object. You might say you are in front of the board, next to another student, or near the teacher's desk.
What is position?

400

To measure the speed of an object, I use the formula:
What is distance divided by time?

400

It is easier to stop a bicycle than a car when both are moving at the same speed in the same direction because:
What is the car has more momentum?

400
