Physics Ch 5 notes
... According to Newton’s second law, the acceleration of the sled is about -1 m/s2 and the time it takes the sled to stop is about 2 s. Thus, the distance the sled traveled in the given amount of time should be less than the distance it would have traveled in the absence of friction. 2.5 m < (2.2 m/s)( ...

Experiment 1-F Ballistic Pendulum and Projectile Motion
... The motion in the vertical direction is subject only to the force of gravity and the ball falls from its initial height H an acceleration g until it hits the floor. Since there is no initial velocity in this direction, the ball’s motion is given by formula (3a). Since we know both H and g, we can us ...

WORK POWER AND ENERGY
... When the force (or a component of the force) is in the direction of the displacement the work is said to be positive. Whenever a force does positive work on the body the velocity of the body increases. In this case it is said that “work is done on the body”. Example : You push some object. As the ob ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
