i have confuse and can't understand what is the defination and equation for constant velocity and constant acce.
Anybody pls help to explain to me pls...
thanx...

Constant velocity refers to the motion of an object at a constant speed and in a straight line. It does not change its direction or speed. On the other hand, constant acceleration refers to the motion of an object that is changing its speed at a constant rate. It can either be speeding up or slowing down, but its acceleration remains constant.
Constant velocity is calculated by dividing the change in displacement by the change in time. This can be represented by the formula v = Δx/Δt, where v is the constant velocity, Δx is the change in displacement, and Δt is the change in time.
Some real-life examples of constant acceleration include a car accelerating from a stoplight, a rollercoaster climbing a hill, and a ball falling towards the ground due to gravity. In all of these situations, the object is changing its speed at a constant rate.
No, an object cannot have both constant velocity and constant acceleration at the same time. This is because constant velocity means the object is not changing its speed or direction, while constant acceleration means the object is changing its speed at a constant rate. These two concepts are mutually exclusive.
Air resistance can affect both constant velocity and constant acceleration. In the case of constant velocity, air resistance can cause an object to slow down due to friction, resulting in a decrease in velocity. In the case of constant acceleration, air resistance can cause an object to reach its terminal velocity, where the forces of gravity and air resistance are equal, resulting in a constant speed.
