Standard IV - Gravity
Standard: Students will understand that objects near Earth are pulled toward Earth by gravity.
Objective 1: Demonstrate that gravity is a force.
Objective 2: Describe the effects of gravity on the motion of an object.
Forces cause changes in the speed or direction of the motion of an object. The greater the force placed on an object, the greater the change in motion. The more massive an object is, the less effect a given force will have upon the motion of the object. Earth's gravity pulls objects toward it without touching them.
