  2. Galileo's law of odd numbers - Wikipedia

    en.wikipedia.org/wiki/Galileo's_law_of_odd_numbers

    In classical mechanics and kinematics, Galileo's law of odd numbers states that the distance covered by a falling object in successive equal time intervals is linearly proportional to the odd numbers. That is, if a body falling from rest covers a certain distance during an arbitrary time interval, it will cover 3, 5, 7, etc. times that distance ...

  3. Galileo's Leaning Tower of Pisa experiment - Wikipedia

    en.wikipedia.org/wiki/Galileo's_Leaning_Tower_of...

    Galileo's thought experiment concerned the outcome (c) of attaching a small stone (a) to a larger one (b) Galileo set out his ideas about falling bodies, and about projectiles in general, in his book Two New Sciences (1638). The two sciences were the science of motion, which became the foundation-stone of physics, and the science of materials ...

  4. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth (i.e., face down) free-fall position is about 195 km/h (122 mph or 54 m/s). [3] This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the ...

  5. Free fall - Wikipedia

    en.wikipedia.org/wiki/Free_fall

    The experimental observation that all objects in free fall accelerate at the same rate, as noted by Galileo and then embodied in Newton's theory as the equality of gravitational and inertial masses, and later confirmed to high accuracy by modern forms of the Eötvös experiment, is the basis of the equivalence principle, from which basis ...

  6. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    Free body diagram of a body on which only gravity and air resistance act. The free body diagram on the right is for a projectile that experiences air resistance and the effects of gravity. Here, air resistance is assumed to be in the direction opposite of the projectile's velocity: F a i r = − f ( v ) ⋅ v ^ {\displaystyle \mathbf {F ...

  7. Timeline of gravitational physics and relativity - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_gravitational...

    Geometric diagram for Newton's proof of Kepler's second law. 1602-1608 – Galileo Galilei experiments with pendulum motion and inclined planes; deduces his law of free fall; and discovers that projectiles travel along parabolic trajectories. [3] 1609 – Johannes Kepler announces his first two laws of planetary motion. [4]

  8. Two New Sciences - Wikipedia

    en.wikipedia.org/wiki/Two_New_Sciences

    The Discourses and Mathematical Demonstrations Relating to Two New Sciences (Italian: Discorsi e dimostrazioni matematiche intorno a due nuove scienze pronounced [diˈskorsi e ddimostratˈtsjoːni mateˈmaːtike inˈtorno a dˈduːe ˈnwɔːve ʃˈʃɛntse]) published in 1638 was Galileo Galilei's final book and a scientific testament covering much of his work in physics over the preceding ...

  9. Idealization (philosophy of science) - Wikipedia

    en.wikipedia.org/wiki/Idealization_(philosophy...

    Galileo used the concept of idealization in order to formulate the law of free fall. Galileo, in his study of bodies in motion, set up experiments that assumed frictionless surfaces and spheres of perfect roundness. The crudity of ordinary objects has the potential to obscure their mathematical essence, and idealization is used to combat this ...
