a head-on elastic collision between a small projectile and a much more massive target, the projectile will bounce back with essentially the same speed and the massive target will be given a very small velocity. One example is a ball bouncing back from the Earth when we throw it down.
An elastic collision is a collision where both the Kinetic Energy, KE, and momentum, p are conserved. In other words, it means that KE0 = KEf and po = pf

The greater the rotation angle in a given amount of time, the greater the angular velocity. Angular velocity ω is analogous to linear velocity v. We can write the relationship between linear velocity and angular velocity in two different ways: v=rω or ω=v/r

Pressure measurement is the analysis of an applied force by a fluid on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum.

The force on the scale has 3 lessons Shrek’s weight, the water weight. the pressure.
The total volume of water collected is V = (1 mm/s)×A × t, and the weight of the water is V × (1000 kg/m3) × g = 10 × t. ,ρ = 1000 kg/m3 is the density of water. therefore F = ∆p/∆t = Mv/t = 1 N
W = 5000 + 1 + 10t.

Linear Momentum
The scientific definition of linear momentum is consistent with most people’s intuitive understanding of momentum: a large, fast-moving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv.

The rotational angular velocity is W This means that, relative to the bottom of the cylinder, the top is moving at speed "2Wr"
The second plate moves to the right at 2ωr faster than the first, and the top plate moves to the right at 6Wr.
top > mid > bottom

The error in k is the same, so dividing a value by five but NOT an error multiplies the error in k by 0.2 observationally.

Set variable by defining z is the height measured from the center of the box and x the horizontal displacement.
Measure from the center of the box. When the ball is in equilibrium at z0 , after having thing set we will use the Hooke's law to calculate the matter.
|
The force responsible for the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. That is, F = −kx, where F is the force, x is the displacement, and k is a constant. This relation is called Hooke's law.
