For example , a top or gyroscope will not fall over when it is spinning. For example , think of the metal ring and the solid disk. The metal ring has its mass at the perimeter and therefore has more rotational inertia than the solid disk. When a force acts upon a body it accelerates that body in the direction of the force. The acceleration produced is directly proportional to the force and inversely proportional to the mass of the body.
Objects move in the direction they are pushed or pulled.
It is easy to push or pull lighter masses. It is harder to move larger masses. Things accelerate more quickly when a greater force is used. For every action or force there is an equal and opposite reaction or force. Any two bodies in the universe attract each other with a force that is directly proportional to their masses and inversely proportional to the square of their distance apart.
