Normal force: for an object resting on the horizontal surface, the upward force that balances the weight of the object; also called the support force picture- The upward force of the table is equal to the downward force of gravity on the book

How to Find Normal Force. Normal force is the amount of force required to counteract the other forces in any given scenario. The best way to go about finding it depends on the circumstances of the object and the variables you have data.

The normal force is the support force exerted upon an object that is in contact with another stable object. This picture shows how even though gravity is pulling the kids down the slide, the normal force is pushing the opposite direction
[Total: 0 Average: 0/5] What Is The Normal Force The external agent which tends to set a body in motion or which changes the speed and direction of motion of a body or which can change the shape of a body is called force. SI unit of force is Newton. Types of Forces: (a) …
coefficient friction: the ratio between the force necessary to move one surface horizontally over another and the pressure between the two surfaces. picture- The red blocks have a higher coefficient of friction because they are closer together
The sum of the forces acting on an object equals zero when the object is moving at constant velocity; W = mg; frictional force equals the component of the weight parallel to the inclined plane (f=mg(sinangle)); normal force euqals the component of the weight perpendicular to inclined plane (mgcosangle); coefficient of friction equals the frictional force divided by the normal force (mg drops out & sinangle/cosangle = tanangle)
