Home is like a shelter where it keeps us safe.
A mechanical wave always consists of wiggles in some kind of material stuff. The material stuff may be air, water, rock, wood, steel ... almost anything, as long as it's some material. In general, whatever the waves are moving through is called the "medium". If there isn't any, like the vacuum in space, then mechanical waves can't travel there. For example, sound can't travel in space ... not even an inch.
Your acceleration is approximately 2.67 m/s squared. It is lower than that of the bear, whose acceleration is 3.75 m/s squared
The kinetic energy of a point body is defined as the product of (1/2) * (m) * (V ^ 2). Therefore, to find the kinetic energy of a body of mass m = 44Kg and velocity V = 10m / s the operation must be done (1/2) * (44) * (10 ^ 2) which results in 2,200 Joules.
Velocity is size and direction
