Air Resistance and Free Fall Experiment

Removing the air from the glass jar

Acceleration is independent of mass

Free fall is the motion of an object under the influence of gravity only, without any other forces acting on it.

<p>Acceleration due to gravity is the acceleration experienced by an object in free fall near the surface of the Earth, which is approximately 9.8 m/s^2.</p> Signup and view all the answers

<p>Inertia is the resistance of an object to changes in its motion. Greater mass leads to greater inertia.</p> Signup and view all the answers

<p>In vertical motion, velocity changes due to the acceleration caused by gravity. When an object is thrown upwards, the velocity decreases until it reaches 0 at the highest point.</p> Signup and view all the answers

<p>Inertia is the tendency of objects to resist changes in their motion. In the context of gravitation and free fall, inertia causes objects to maintain their velocity unless acted upon by an external force, such as gravity.</p> Signup and view all the answers

<p>Acceleration due to gravity is the acceleration experienced by an object in free fall due to the gravitational force of the earth. It causes objects to fall towards the earth with a constant acceleration of approximately 9.8 m/s^2.</p> Signup and view all the answers
