Assuming that the traction of the sprinkler is constant, and the resistance is proportional to the weight of the vehicle. When the sprinkler is not sprinkled, the vehicle moves in a straight line at a constant speed; when the sprinkler is sprinkled, its motion will change 1 uniform acceleration 2 variable acceleration It's 1 Or two Or both

2. Because the traction force remains unchanged, the resistance decreases, and the resultant force gradually increases. When the resultant force is zero, the velocity will be constant, constant and gradual

Assuming that the traction of the sprinkler is constant, and the resistance is directly proportional to the weight of the vehicle, when the sprinkler is not sprinkling, the car runs at a constant speed, and its motion will be ()
A. Do variable acceleration linear motion B. do uniform acceleration linear motion with initial velocity not zero C. do uniform deceleration motion D. continue to do uniform linear motion

Let the traction force of the sprinkler be f, the mass of the sprinkler be m, and the resistance be KMG. According to Newton's second law: f-kmg = Ma: a = FM kg. At the beginning, f = KMG, a = 0. With the decrease of M, a gradually increases, so the liquor tanker does the acceleration motion of gradually increasing acceleration

What's the relationship between the drag and the traction when the car accelerates in a straight line? Please tell me more about the relationship between the drag and the traction

Why did you learn this in grade two
Acceleration driving: traction is greater than resistance
Driving at a constant speed: traction equals resistance
Deceleration driving: traction is less than resistance
(the above is the relationship between traction and resistance of the car in the horizontal direction without the influence of other external forces)
