If the speed is constant, then the group of forces acting on the object is balanced.
So the portion of the force acting in the direction of the motion must be equal and
opposite to the force of friction.
It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.
If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
If traveling at constant speed in a constant direction then net force is zero as there is no acceleration. Acceleration would change one or the other, or both. F = ma = m (0) = 0
The net force on the car acts on the line between the center of the car and the center of the circle. Its strength depends on the size of the circle and the speed of the car.
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.
The magnitude of the force of friction on the crate is equal and opposite to the force you apply to push it, as long as the crate is moving at constant speed. This is because the force of friction balances the push force to prevent acceleration.
The force on a mass moving at a constant speed and direction is 0.
The magnitude of the force of friction on the crate would be equal to the magnitude of your push. This is because the crate is moving at a constant speed, indicating that the force you are applying is balanced by the force of friction acting in the opposite direction.
When a lorry is moving at a constant speed, the driving force provided by the engine is balanced by the resistive forces acting against it, such as friction, air resistance, and road resistance. This equilibrium allows the lorry to maintain a constant speed.
As a cyclist goes faster, the force of friction remains relatively constant. The force of friction between the tires and the road depends on the coefficient of friction and the normal force, which do not change significantly with speed.
The net force on a car moving at a constant speed in a straight line is zero. This is because the forces acting on the car, such as friction and air resistance, are balanced by the force produced by the engine to maintain the constant speed.
The force applied to slide the box down at a constant speed is equal to the force of kinetic friction acting against the box. This force is given by the equation: friction force = coefficient of kinetic friction * normal force. Since the box is sliding down the wall, the normal force is equal to the weight of the box. Therefore, the force applied is equal to the coefficient of kinetic friction * weight of the box.
It is equal to the retarding force due to friction.
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
Thrust and friction in the environment. Ignoring friction, the two chief factors are the force of acceleration and mass, which determines how much force is required to achieve a given speed (more technically the change of velocity: speed in a given direction).
It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.
