... Example: A cyclist, C, travelling at 6 m s-1 sights a walker, W, 500 m due east. The walker is travelling at 2 m s-1 on a bearing of 310o. There are no obstacles and both the cyclist and the walker can travel anywhere. What course should the cyclist set in order to meet the walker, and how long will ...

If this force increases, the hills and valleys of the surfaces can come into closer contact. • The close contact increases the friction between the surfaces. ...

Acceleration and Newton`s Second Law
... The velocity of an object includes both its speed and the direction it is moving. A car with a velocity of 20 m/sec north has a speed of 20 m/sec and is moving north. An object accelerates if its velocity changes. This can occur if its speed changes or if its direction changes (or both). Therefore, ...

Systems of particles
... The centre of mass is fixed in the rod, so y12 and y22 are constant. The external torque about the centre of mass being zero therefore implies that ω is constant, so θ̇ is constant in the motion, where θ is the angle the baton makes with the vertical, and |θ̇| = |ω|. The time lapse photograph below ...

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.
