The velocity increases due to the fact, the ramp is facing downwards in a certain angle.
The longer the ramp, the faster the cart will travel!
If the mass of the cart is increased, the kinetic energy of the cart will also increase as it rolls down the ramp. The velocity of the cart will increase as well, since the kinetic energy is directly proportional to both mass and velocity squared.
The three situations for changing velocity are speeding up, slowing down, or changing direction.
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
An object changing direction is an example of acceleration. When an object changes its velocity, either by speeding up, slowing down, or changing direction, it is experiencing acceleration, which is the rate of change of velocity.
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.

Changing velocity involves either increasing or decreasing speed, or changing direction. This can be achieved through acceleration, which is the rate of change of velocity over time. In other words, when an object speeds up, slows down, or changes its direction, its velocity is changing.
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Yes, the rate of change of velocity is equal to acceleration. This means that if an object's velocity is changing, it is experiencing acceleration, either by speeding up, slowing down, or changing direction.

The cart will move at a constant velocity.
Something is decelerating . I.e it's still going forward, but at a reduced and falling speed.
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
