... The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block (of wood or other material) of mass M, which is suspended like a pendulum. (Usually, M is somewhat greater than m.) As a result of the collision, the ...

Summary of Chapters 1-3 Equations of motion for a uniformly acclerating object
... A force is a push or a pull acting on an object. A force is a vector! Contact forces arise from physical contact, and are due to stretching or compressing at the point of contact. Action-at-a-distance forces do not require contact and include gravity and electrical forces. ...

... • The acceleration is constant for all objects in free fall. During each second of fall the object gains 9.8 m/s in velocity. • This gain is the acceleration of the falling object, 9.8 m/s2, or 32 ft/s2. The symbol g is used for this. Thus g= 9.8 m/s2, or 32 ft/s2 • The acceleration of free falling ...
