Mr. Biando's Lab - Gravity and Motion
| Definition | Term |
|---|---|
| In the 1500s this Italian scientist tested his hypothesis that all objects regardless of their mass fell at the same rate of speed due to gravity. | Galileo |
| The rate of acceleration due to gravity. | 9.8m/s2 |
| gravity multiplied by time. | the change in velocity |
| The force that opposes the motion of objects through the air. | Air resistance |
| The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity. | Terminal velocity |
| The motion of a body when only the force of gravity is acting on the body. | Free fall |
| Any object that travels in a circular path around another object. | Orbiting |
| Unbalanced forces that cause an object to move in a circular path. | Centripetal Force |
| The curved path that an object follows when thrown, launched, or otherwise projected near the surface of the Earth. | Projectile Motion |
| The component of projectile motion in which motion of the object is parallel to the ground. | Horizontal motion |
| The component of projectile motion in which the object moves perpendicular to the ground. | Vertical motion |
