skateboard
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
skateboard.....if velocity is zero,then momentum is also zero.
Forward to the direction your moving
In physics, the kinetic energy of an object is the energy that the object possess, due to the fact that the object is moving. When the object/skateboard isn't moving it has no kinetic energy. However when it is given energy such as a push, it would move and keep going until it is stopped by another force, such as a wall.
you hold shift while moving
When all forces are balanced, the object can either be moving at a constant velocity or be at rest. But because you asked for balanced forces on a moving object, it is moving at a constant velocity.
An object at rest cannot start moving with no forces.
first Newton law of motion
Forces that likely act upon a moving object include:frictiongravity
Inertia keeps you moving forward.
forces of body depends on the path it is moving for example if it is moving in straight path it under go forces like frictional forces and forces applied on it if the body is moving in slant path it has frictional force,acceleration due to to gravity(which acts down wards)
