Free Body Diagram: A sketch where a body is cut free from the world except for the forces acting on it. In the bridge example the free body diagram for the top of the tower is: Free Body Diagram It helps us to think clearly about theforces acting on the body. Example: Car on a H...

So the net force on the car is 4800 Newtons. 3. If an object is in equilibrium, then its net force is zero by definition. Since the object is in equilibrium, it is not accelerating and so a = 0. Since this object is moving, but has acceleration 0, the object must be moving at ...

In a very similar way as we saw above for the longitudinally accelerating car, an equilibrium diagram can be prepared for the laterally accelerating car, and this is shown in Fig. 3.4. The centripetal force, maY, is balanced by the lateral forces μFZO and μFZI. Sign in to download fu...
a system experiences no acceleration when it is either at rest or moving at a constant speed in a straight line. However, remember that even though the car turns at a constant speed – because, to trace a circle, it must change its direction constantly — it is accelerating. Such a frame...
If a car is accelerating, what forces would be applied on the object? There is a 15 kg object sitting on a surface. The coefficient of static friction is 0.300. According to Newton's Second Law, how big will the acceleration be if it is pushed with a 2.5 N force?
The equations used for acceleration can also be used for calculating braking distance and time, except that the accelerating force Fa becomes the gross braking force Fb. Force Fb is equal to the brake shoe pressure plus train and curve resistance (if any) plus or minus grade resistance. The ...
the object will keep moving faster and faster. The reason things do not keep accelerating is that all kinds of opposing forces get bigger with speed. That’s why there is a terminal velocity for skydivers: gravity alone would keep making the free fall speed faster, but air resistance eventua...
An object in UCM is accelerating toward the center of the circle. This is known as a centripetal (center-seeking) acceleration. The force causing this acceleration is known as a centripetal force. The magnitude of centripetal acceleration is equal to the square of velocity divided by the radius...
