that's FRICTION my child
upthrust
The engine causes the tires of the vehicle to turn. The tires are made of rubber in order to maximize the friction (traction) between the tires and the concrete. It is the tires and the force of friction which causes a vehicle to move forward (or backward, for that matter).
When a boat is moving at a constant velocity on a flat surface, the forces acting on the boat are balanced. The force of propulsion forward is equal to the force of drag resistance opposing motion, and the force of buoyancy is equal to the force of gravity acting on the boat.
When a car is moving in the forward direction, the main forces at play are the engine force propelling the car forward, the frictional force between the tires and the road providing traction, and air resistance acting against the car's motion. These forces work together to keep the car moving in the desired direction.
1) There are always frictional forces, which by themselves would slow the car down. 2) Since we are assuming that the car is moving at a uniform speed, there must be another force to compensate for the friction, and in the opposite direction (pulling the car forward). This force is related to the effort done by the engine.
This is not a force, but your conservation of momentum. For there to be a force, you must have some acceleration, but what you feel is actually your body attempting to continue moving forward until the force of friction and force normal of your seat belt decelerate you.
Yes, frictional forces such as air, tires against the ground, gravity pulling the car down, force of engine moving car forward. The positive force of the engine turning the drive train and the wheels is equaled by the frictional forces; so overall forces balance out.
To move an object forward from rest the thrust of forward force must be greater than the drag acting in the opposite direction. In order to keep moving at a constant velocity the forward force must equal the drag.
The main forces acting on a moving skateboard are friction with the ground, air resistance, and the force applied by the skater to propel the skateboard forward. Additionally, there may be gravitational forces affecting the vertical motion of the skateboard.
No, centripetal force is not acting when a body is moving in a straight line. Centripetal force is required to keep an object moving in a curved path.
It is the force of inertia.
The ball keeps moving forward because of its momentum, which is not a force.
