What causes a box to slide across the bed of a truck when the truck accelerates forward? - bed slide
A large field is laid in the bed of a truck, but not appropriate.
When the car accelerates, the field sheets on the bed until it hits the back door. Explain why.
Help? Thanks
Also, if you can ....
Explain why pull the rope a climber has the rope down to move up. Discuss the force exerted by the arms of the climber under the weight of the climber in the various phases of each step, by the rope.

This is due to the inaction of the rest.
When the car accelerates, respect a force on the field in the opposite direction of the car.
Standard technique to find the person relative WRT is first and foremost, we should do one for the position by applying an equal and opposite vector. The same applies to the amount of a parent, if applicable.
For example, say a car and B with a speed of 50 km / h 20 km / h in the same direction. The relative speed of a car WRT B, B, to find peace through the implementation of 20 km / h vector in the opposite direction as back The same is true for cars vector km / A. 20 h prior to 50 km / h and so is the profit 30 mph in the direction of motion of the face. This means that the car appears at a speed exceeding 30 km / h for the moving observer in carbohydrates.
When moving a car and car B in opposite directions, with a maximum speed of 40 and 30 km / h, the relative velocity of AB WRT 40 +30 = 70 to be km / h.
The same technique. B is at rest by the application of 30 km / h in reverse. SAMe 30 km / h is it, given A. But even in the opposite direction. Therefore, he added. We get 70 km / h relative speed.
Thus, in the same way, in our example is the truck alone to determine the relative motion of the truck-WRT box. Thus the image in the opposite direction with the same acceleration is to move and then finally take the door of the glue used.
2) It is the third law must be applied. As a reaction to every action is an equal and opposite. They say that the weight of the climber W. Therefore, we must pull the string with the same force W in the downward direction, which in turn is the third law, a lifting force W and upwards. When the hand of a force equal to the weight and much more.
1. Friction is trying to keep the field in the direction of the acceleration of the car.
If the field is not the friction force is moving in the direction of the acceleration of the car.
db first phenomenon can be explained by the first law of Newton. d-Box has inertia.
Seconds are by d Third Law explains.
