Inertia (Newton’s 1st Law) is the resistance of an object to change its motion. Would an object with more mass or less mass have more inertia?

• More mass

• Less mass

The mass of objects, and the distance between the objects determines the strength of the gravitational pull between them. Which relationship below is true?

• More massive objects and closer objects have a greater gravitational pull.

• More massive objects and far-away objects have a greater gravitational pull.

• Less massive objects and closer objects have a greater gravitational pull.

What are the variables from the graph?

• Independent (manipulated) variable: Day of the Month, Dependent (responding) variable: amount of Rainfall

• Independent (manipulated) variable: amount of Rainfall, Dependent (responding) variable: Day of the Month

What question could the student be investigating

• Does the day of the month determine the amount of rainfall?

• Are there days of the month when rainfall is heavier than others?

If there is no external force on a moving object, it will…

• Maintain the same state of motion.

• Keep moving with a constant velocity.

• Move in a straight line but stop eventually.

• Change Direction and then stop

Net Force is the sum (total) force that is acted on an object. If the object is not moving the net force is at 0 and if the net force is not 0, the object is moving.

• True

• False
