Want this question answered?
A car moving at constant speed in a straight line is also moving at constant velocity.
balenced
if an object is moving without any net force or acceleration, it is moving at constant speed, or constant velocity. For example a satellite orbiting the earth is moving at constant speed, a car traveling at 60 mph, a wind of 20 mph. etc.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
car is not always moving at constant speed
A car moving at constant speed in a straight line is also moving at constant velocity.
No it does not because once you change direction you do not have a constant speed.

Yes. The degree and slant of the ramp does affect the speed of the car
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
If the speed is constant at 50 mph, then the acceleration is 0.
More gas is used when you accelerate, that's why using cruise control is a gas saver, it keeps your vehicle at a constant speed.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
I wonder what is the constant speed of this moving car
The velocity of the car is staying constant speed the whole time. It is not rising or diminishing at all.
Not necessarily. Constant velocity also means no change in direction.
