HOW GALILEO INFERRED THAT OBJECTS IN VACUUM

• MOTION OF OBJECTS IN A VACUUM -Galileo deduced that in the absence of air resistance or other external forces, all objects fall with the same constant acceleration due to gravity. Objects in a vacuum fall with uniform acceleration.
• GALILEO'S PERSPECTIVE ON HORIZONTAL MOTION - once an object is given an initial velocity, there is no force acting on it to slow it down or change its motion. Therefore, the object will continue to move horizontally at a constant velocity indefinitely.
• FREE FALL ACCELERATION - refers to the constant acceleration experienced by objects that fall freely under the influence of gravity, in the absence of any other external forces such as air resistance.
• LEANING TOWER OF PISA -Galileo dropped cannonballs from the leaning tower of Pisa to conduct his experiments on falling bodies. These experiments involved rolling objects of different masses down inclined planes with carefully measured angles to observe their motion.
• INCLINED RAMPS -Galileo used inclined ramps to measure the acceleration of objects, particularly for studying the motion of rolling balls. By rolling objects of various masses down inclined planes with carefully measured angles, Galileo could observe how the acceleration due to gravity affected their motion.
• GALILEO'S INCLINED PLANE EXPERIMENTS- were instrumental in his understanding of acceleration and the effects of gravity. Galileo infer that the objects in vacuums fall with uniform acceleration by observing the motion of objects on an inclined plane.
• GRAVITY- leads the object to accelerate at a constant rate, this concept is known as uniform acceleration due to gravity.
• UNIFORM ACCELERATION -By observing a feather and a hammer falling at the same rate in a vacuum chamber, Galileo inferred that an object in a vacuum fall at a uniform acceleration.
• OBJECTS IN A VACUUM- will fall at the same time regardless of their weight. Galileo observed that objects of different masses, when dropped from the same height in a vacuum or under conditions where air resistance was negligible, reached the ground at the same time.
