The weight of the sled affects the force needed to pull it because the greater the weight, the more force is required to overcome the force of gravity and move the sled. In this case, the weight of the sled is 100kg, so a considerable amount of force will be needed to pull it.
The force needed to pull the sled is influenced by various factors such as the weight of the sled, the surface it is being pulled on, the angle of the pull, and any friction present. These factors affect the overall resistance to movement and therefore impact the force required to pull the sled.
The force needed to pull the sled can be calculated using Newton's second law of motion, which states that force equals mass times acceleration (F=ma). In this case, the mass of the sled is 100kg, and the acceleration is the force needed to overcome resistance and move the sled.
No, the force needed to pull the sled is not constant. As the sled moves, the force required to overcome resistance may vary depending on the surface, incline, and other factors. The force needed to start moving the sled from a stationary position will also be greater than the force needed to keep it moving at a constant speed.
If the weight of the sled is increased, the force needed to pull it will also increase. This is because a larger mass requires more force to overcome resistance and move. Doubling the weight of the sled, for example, would require twice the force to pull it at the same speed.
