Is any work been done on a car moving with a constant velocity along a perfectly straight perfectly smooth and horizontal road?
According to work energy theorem, the work done by the car is zero. Since the kinetic energy does not change and the car is moving along a straight horizontal road the work done is zero only if there is no non conservative force like friction. If there is friction then work done will be force into displacement.
What type of motion does a car traveling along a straight highway at a constant speed have?
Constant motion is a type of motion that occurs when either the distance traveled by the object is the same for each second or the speed of the object changes by the same amount each second. A car maintaining a speed of 20 meters per second as it moves in a straight line for 5 seconds is in constant motion.
What forces act on a car as it is moving?
Every vehicle, whether it’s a car, truck, boat, airplane, helicopter or rocket, is affected by four opposing forces: Thrust, Lift, Drag and Weight (Fig. 1).
Is there any net work done by external force on a car moving with a constant speed along a straight road?
No, when a car is moving with constant speed on a straight road net-work done by external forces will be zero. Q. Solve the following problems.
When an object traveling along a straight has a constant velocity?
Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt, where x0 represents the position of the object at t=0, and the slope of the line indicates the object’s speed.
What kind of motion when a car moving with constant speed turning around a curve?
The type of motion that a car exerts while moving with a constant speed and turning around a curve is uniform circular motion and the electron orbitting the nucleus exerts the same kind of motion.
What is the motion of a car along a straight road?
A car is said to be in rectilinear motion if it moves on a straight road.
What is the motion of a car along a straight line?
A car moving on a straight road is an example of rectilinear motion.
What kind of motion is linked with the following a car moving along a straight road?
When the vehicle is moving on a straight road, it is following a straight-line path. Thus, the given motion is rectilinear motion.
What is the pitch of a car?
Pitch is a shift in your vehicle’s weight forwards or backwards. When it happens, the weight is moving from one end of the vehicle to the other – from the back to the front or from the front to the back.
How is weight and mass difference?
Mass is the measure of the amount of matter in a body. Mass is denoted using m or M. Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity. Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).
Is stationary a speed?
If the forces on an object are balanced, its speed will not change. If it is stationary (speed = 0), then it will stay stationary. If it is travelling at 4km/h, it will stay at 4km/h. If the forces acting on an object are unbalanced, its speed will change.
Is there work done if velocity is constant?
If a body is moving with a constant velocity, the net force on it is zero. So the net work done on it will be zero.
When a car moves along a horizontal road with constant velocity?
A car moves along a horizontal road with constant velocity v0 = v0xi until it encounters a smooth inclined hill, which it climbs with constant velocity v1 = v1xi + v1yj as indicated in the figure. The period of time during which the car changes its velocity is Δt.
Can a car move at constant velocity?
Answer and Explanation: If a car is moving with a constant velocity, then it is also moving with a speed that is constant. Note that the confusion between the two rates, which are actually measured in the same units, is this: velocity is a vector quantity, while speed is a scalar quantity.
Does the engine of a car moving in horizontal road in uniform speed do any work?
Force applied by the engine of the car against friction maintains its uniform velocity . This force is doing work as displacement occurs against frication. If f= force of friction and v=velocity of the car, work done in 1s by the engine = force of friction × constant velocity =fv.
