When walking up a hill, you are primarily using the force of gravity to overcome the incline. Your muscles work against gravity to propel you forward and upward. Additionally, you may also use friction between your feet and the ground to help maintain stability and prevent slipping.
The resistance force when walking up a hill is the force acting opposite to the direction of motion, mainly due to gravity pulling you downward and air resistance pushing against you. It makes it harder to move uphill because you have to work against these forces to overcome the resistance and move upwards.
Running up a hill requires more force to overcome gravity and friction compared to walking, therefore more kinetic energy is needed. Running also involves larger muscle contractions and faster movements, leading to a greater expenditure of energy.
A road going up a hill is an inclined plane simple machine. It reduces the amount of force needed to move up the hill by increasing the distance over which the force is applied.
While, if the hill is 90 degrees, then it is a cliff. That is to say, that you are not receiving any "help" from the 90 degree hill. You are just lifting the object straight up. Whereas the 20 degree hill provides a ramp.
Friction is the force that allows you to walk up a hill without sliding back down. The friction between your feet and the surface of the hill provides the necessary grip to overcome gravity and maintain your position.
The resistance force when walking up a hill is the force acting opposite to the direction of motion, mainly due to gravity pulling you downward and air resistance pushing against you. It makes it harder to move uphill because you have to work against these forces to overcome the resistance and move upwards.
Running up a hill requires more force to overcome gravity and friction compared to walking, therefore more kinetic energy is needed. Running also involves larger muscle contractions and faster movements, leading to a greater expenditure of energy.
Tightening a screw, or a nut and bolt. Walking up a hill.
Walking up a steep sand hill with fragile and shallow rooted plants could damage that part.
A road going up a hill is an inclined plane simple machine. It reduces the amount of force needed to move up the hill by increasing the distance over which the force is applied.
No. The car is applying a force to keep going up the hill and the hill and car are providing forces to keep it up.
Walking up a hill requires your muscles to work against gravity, leading to more effort and energy expenditure compared to walking on level ground. The incline of the hill increases the vertical lifting component of walking, which adds additional resistance and makes it more difficult to move forward.
Same reason as walking up stairs is hard - you have to overcome gravity.
Hug the side where there is a turn.
The riddle describes a person who uses a cane or walking stick for support. The "three legs" refer to the two human legs and the cane, while "walking up a hill on 2 legs" indicates that the person is walking upright, using the cane as an extra support.
down the hill. the force of gravity pulls you down.
it is a sloping ramp up which heavy loads can be raised by ropes or chains like walking up a huge hill
