skateboard. momentum is mass times velocity thus if 0 velocity=0 momentum

The momentum of any object depends on its mass and its speed. If a car and a bike are both moving at the same speed, then the car has more momentum because it has more mass than the bike. If the car and the bike are moving at different speeds, then we need to know the speeds of each, in order to make any determination about their respective momenta.
the slower one has more energy because it does not use it all moving.

Energy. Two objects with the same momentum can have different kinetic energy. Example - A 1 oz projectile at 1000 ft/s and a 10 oz projectile at 100 ft/s have the same momentum. The lighter projectile has 10 times as much kinetic energy as the heavy projectile. Example - A 1 oz projectile at 1000 ft/s and a 100 oz projectile at 100 ft/s have the same kinetic energy. The heavier projectile has 10 times as much momentum as the lighter projectile. Momentum = m*v. Energy = (m*v*v)/2.
Momentum.
Momentum is a function of both mass and speed. The wrecking ball isn't moving very fast, but it is extremely heavy; that is where its momentum comes from.
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
A heavy football player is harder to stop because it has a greater momentum. In physics, momentum is equal to the mass of an object times its velocity. If a 50 kilogram kid and a 70 kilogram man were running at the same speed, the man would be harder to stop because he would have a greater momentum.

No. Even a single electron has momentum.
Momentum
Momentum = Mass x Velocity. They could have the same momentum if the motorcycle is going fast and the van is going slow. If the van weighs ten times as much as the motorcycle, and is driving 5 mph it would have the same momentum as the motorcycle driving 50 mph.
no, it simply has to have mass.
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
No. Moving slowly against resistance is a tactic primarily for advanced bodybuilders. On the other hand, what you do not want to do is to use momentum. The weight should always be under full control as you lower and raise it.Actually, in power lifting, speed is an important component of doing well. Many power lifters practice moving heavy weights quickly but without using momentum.
