Total: 5300 Forces acting on a car moving at a steady speed Resultant force

Forces acting on an object can be substituted with a single force, the resultant force The loaded truck accelerates slower, therefore it has a greater inertia Free fall of a spacecraft Space Station There are forces acting on them and as a result they start to move Scale

In physics, scales represent the system of gradually growing values. Forces can have different strengths A boy playing football Determining the volume of solids In force diagrams the force is represented by an arrow Isaac Newton (1643-1727), English physicist The extension of the spring is directly proportional to the force applied to it The fully compressed spring exerts a greater force Two-pan balance During hammering not only the object's shape changes but also its temperature rises It is easier to understand the increase of gravitational energy if we theoretically connect an object to Earth with a spring that represents the gravitational field When the boy releases the ball, it rises in the air and the gravitational field increases, and when the ball falls through the basket, the gravitational field decreases The energy of the electric field is reduced when the bulb flashes
