An example of constant motion is a car driving at a constant speed on a straight road.
"Constant" means that the speed doesn't change over time.
Divide the distance travelled by the speed...
Constant motion is when an object maintains a steady speed and direction over time, like a car driving at a constant speed on a straight road. Non-constant motion is when the speed or direction of an object changes over time, such as a car accelerating or turning.
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
An example of a car moving at constant speed and constant velocity would be a car driving along a straight road with no change in direction, where the speedometer shows a steady reading, and there are no changes in velocity or direction of motion. This means the car is moving at a consistent speed in a straight line without any acceleration or deceleration.
The car will eventually reach a new higher constant speed when it travels downhill due to the force of gravity pulling it downward, causing an increase in its kinetic energy. Once the car reaches this new constant speed, the forces acting on it, such as air resistance and friction, will balance out to maintain the new higher 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.
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.
A car moves at a constant speed when the acceleration is zero. This means that neither the speed nor the direction of the car is changing. Once all external forces are balanced and there is no net force acting on the car, it will continue to move at a constant speed.
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.
Straight line at a constant speed = no acceleration
