How does a speedometer needle move when a car is moving with constant velocity speeding up and slowing down?
When a car is moving with constant velocity, the speedometer needle will remain steady and point to a consistent speed. When the car speeds up, the needle will move clockwise to reflect the increase in speed. Conversely, when the car slows down, the needle will move counterclockwise to indicate the decrease in speed.
How does a speedometer needle moves when a car is moving with constant velocity seeding up and slowing down?
When a car is moving with constant velocity, the speedometer needle will stay steady at a particular speed. When the car is accelerating, the needle will move clockwise indicating an increase in speed. When the car is decelerating, the needle will move counterclockwise indicating a decrease in speed.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Why forces acting on a car as it moves along a level highway in still air at a constant speed?
The main forces acting on a car moving at a constant speed on a level highway in still air are the driving force from the engine propelling the car forward and the opposing forces such as friction between the tires and the road and air resistance. When these forces are balanced, the car will continue to move at a constant speed.
Does a car accelerate rounding a curve at a constant speed?
No, a car does not accelerate when rounding a curve at a constant speed. Acceleration occurs when there is a change in speed or direction. In this case, the car is moving at a constant speed but is changing direction, not accelerating.

An object will move at constant speed until?
An object will move at constant speed until acted upon by a force.
Does a car moving around the block drives at constant velocity?
It could move with a constant speed and not at constant velocity. Because the direction is ever changing. Speed is a scalar but velocity is a vector quantity which has direction aspect too.

What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
Is it correct to assume a motion of constant speed?
It depends on your setting. If the net force on an object is zero than the object will move with a constant speed. It will also move with a constant speed (but not velocity!) if a force forces the object to move in a circular motion.
If the sum of all the forces acting on a car is zero then the speed of the car always?
If the sum of all the forces acting on a car is zero, it means that the car is in a state of equilibrium. In this case, the car will either be at rest or moving at a constant speed. If the car is already moving at a certain speed, it will continue to move at that speed due to the balance of forces acting on it.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
What are examples for zero acceleration?
Anything that doesn't move; anything that moves at a constant velocity (for example, a car on a straight road, at a constant speed of 70 km/hour).
