Speed and Velocity
... You can show the motion of an object on a line graph in which you plot distance versus time. Time is shown on the horizontal axis, or x-axis. Distance is shown on the vertical axis, or y-axis. A point on the line represents the distance an object has traveled at a particular time. The x value of the ...

Section 4: Conservation of (Mechanical) Energy
... Kinetic energy represents “energy of motion”. The faster an object moves, the more kinetic energy it has. If we apply a constant net force to an otherwise free particle it will accelerate with constant acceleration because . Remember that with constant acceleration we showed earlier that over some t ...

Balanced Forces
... Notice that all the forces are unequal and pointed in the opposite direction. Hence they are unbalanced and in opposition to each other – or one partially cancels the other. ...

Work, Energy and Power
... • The friction force is μkN = -10.6 N, the negative sign indicates this force opposes the motion. The work done by the friction force is (-10.6 N)(20 m) = -212 J • Work done by x component of the weight = -(24.5 N)(20 m) = -490 N • Net work = 0 + 1600 J – 212 J -490 J = 898 J ...

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.
