- Normal force
- First law. The person is at rest and will stay at rest until being acted upon by an unbalanced force.
- Gravity
- Air Resistance
- Second Law. The acceleration of the truck may be slower than a race car because it has so much more mass. Second law states how the acceleration of an object depends on the mass of the object and the amount of force applied. So, A truck and a race car may have equally powerful engines, but because a truck has so much more mass it accelerates a lot slower.
- Velocity : 30 m/sAcceleration : of 0.6m/s^2
- The engine force is F_e while the opposing friction force would be F_f. This means that the net force would be ΣF = F_e - F_f. This net force is applied onto the truck while it is moving.
- Friction
- Gravity
- Road pushing
- Normal Force
- Thrust
- Normal force
- Gravity
- Inertia will also cause the driver to be flung forward because of the sudden stop.
- Friction
- Drag
- Begins braking but the friction doesn't provide enough force to slow down the truck because of the momentum
- Normal Force
- Gravity
- Momentum
- First Law. The person will stop being at rest and begin moving because he got hit with an unbalanced force.
- The net force of the truck gets transferred into the person.
- The truck will keep moving because the person didn't provide a unbalanced force to cause the truck to stop.
