i am confused about the exact forces in play while we walk and while a car is driven, can anybody please show me a free body diagram regarding these with explanation? Also, which force does work when we walk?
Thnx
Thnx

Walking and driving both involve the application of forces, but the main difference is that walking relies on the force of friction and driving relies on the force of propulsion. When we walk, our feet push against the ground and the friction between our feet and the ground allows us to move forward. When we drive, the force of the car's engine propels the car forward.
The force of gravity affects both walking and driving. When we walk, gravity pulls us towards the ground and we must use our muscles to overcome this force and stay upright. When we drive, gravity still pulls us towards the ground, but the force of the car's engine counteracts this force and allows us to stay on the road.
Friction is crucial in both walking and driving. When we walk, the friction between our feet and the ground allows us to push off and move forward. When we drive, the friction between the tires and the road allows the car to grip the road and move forward without slipping or sliding.
In addition to friction and gravity, there are other forces that play a role in walking and driving. These include inertia, which is the tendency of an object to resist changes in motion, and air resistance, which affects objects moving through the air, such as a car driving at high speeds.
The surface we walk or drive on can greatly affect the forces involved. For example, walking on a slippery surface like ice requires more force to maintain balance and propel ourselves forward. Driving on a rough or uneven surface can also require more force to maintain control of the car.
