# How would the velocity of an object change when the speed stays the same?

Velocity includes both speed and direction, so velocity will change when an object changes direction while maintaining it's speed. An example is a car at constant speed around a curve.

same speed , coz velocity is constant velocity consists of speed and direction...

For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).

That depends on the situation. If the object is moving freely in a vacuum, the speed stays the same. If an object is accelerating, the speed change depends in part, on the mass of the object.

Acceleration is a change in velocity with respect to time. Velocity is a vector quantity, meaning it has both a direction and a speed. Acceleration is therefore also a vector quantity. So if you change the direction an object is moving without changing its speed, you are still accelerating the object.The best example of this is circular motion. If you tie a string to a rock and swing around your head at a steady rate, the speed of the rock stays the same but its direction is continually changing. It is accelerating, and the acceleration vector points directly to the center of rotation.

That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.

because it wont be as heavy when it stays having the same velocity

Terminal. It stays at that one velocity til the object hits the ground.

Zero net force on a object means that the velocity of the object stays constant (this includes 0, when the object is not moving). Lets look at Newton's 2nd law of motion: Fnet=ma An object can never have a 0 mass (then it wouldn't exist). Therefore, the acceleration has to be 0 for the net force to be zero. Recall at acceleration is the change of velocity over time. In order for the acceleration to be zero, the velocity has to be constant. If the object is at 0 velocity (not moving), the object would remain unmoving when a net force of 0 is applied to it. If the object is moving at a certain velocity, it would remain at that velocity. Therefore, a zero not force cannot do anything to an object.

momentum = mass * velocity As the momentum changes with constant mass, the velocity cahnges.

It cannot go any faster. It's acceleration drops to 0 and the velocity stays constant.

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with constant velocity unless acted upon by an unbalanced force. This is also called the law of inertia. So, the forces acting on an object are balanced when the object is not accelerating. This happens when the object is at rest, or when the object is moving at constant velocity. ===================== The forces on an object are balanced when their vector sum is zero.

No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

An object that stays at rest, stays at rest and an object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced force

The momentum stays the same. The mass increases and the velocity decreases but the momentum stays the same, momentum is conserved.

is the type of speed that does not change or stays constant

Velocity = Frequency * Wavelength. If the wavelength increases and the frequency stays the same, then the speed of the wave will increase.
