If the angle (theta) is ideal for the speed and radius, then the net external force equals the necessary centripetal force. The only two external forces acting on the car are its weight (vec{w}) and the normal force of the road (vec{N}). (A frictionless surface can only exert a force perpendicular to the surface—that is, a normal force.)

WhatsApp: +86 18221755073When multiple forces act on an object, the forces combine. Adding together all of the forces acting on an object gives the total force, or net force. An external force is a force that acts on an object within the system from outside the system. This type of force is different than an internal force, which acts between two objects that are both ...
WhatsApp: +86 18221755073There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book. Since these two forces are of equal magnitude and in opposite directions, they balance each other.

WhatsApp: +86 18221755073Friction is a force that opposes motion. It's proportional to the normal force acting between an object and the ground. In winter, you apply sand on icy surfaces to increase friction and prevent slipping.

WhatsApp: +86 18221755073What kind of force is needed to make the swing move? When the swing moves from the lowest point up to either peak, the main force acting is momentum; and when the swing falls from either peak to its lowest point, the main force acting is gravity. If you do not pump your legs fast enough, air resistance along with gravity will keep you down.
