Is curve an adjective?
No, curve is not an adjective.Curve is a verb, e.g. The road will curve to the left up ahead.It can also be a noun, e.g. There is a sharp curve in the road up ahead.The adjectival form of curve is curved, e.g. That road is sharply curved.Curved can also be a verb, e.g. The road curved to the left.

Which of the following best describes a plane?A. A curve in a roadB. The point of intersection of two wallsC. The surface of a flat tableD. The edge of a desk
A car moves in uniform circular motion around a curve in the road What is the direction of the car's acceleration?
If the speed is constant, the acceleration is toward the center of the circle.
What is a inclined plane and example?
An example of an inclined plane is a ramp, slanted road, or a slide. An inclined plane is a surface that is at an angle against a horizontal surface.
How do I find the speed of a vehicle when all I know is the length of the skid marks 24.2 metres and the pavement was wet at this time with a very slight slope down?
To find the speed you would need to find the time taken to create the skid marks and then use the equations of motion. As the vehicle is skidding, the wheels are not turning so the braking force is the friction between the tyre and the road surface; this has to overcome the forward speed of the vehicle and the forward force of the weight of the vehicle along the road (as there is a downward slope). The forward force of the vehicle can be calculated by knowledge of the mass of the vehicle and the angle of the slope. The frictional force generated can be calculated from the coefficient of friction between the tyres and the road surface, and the mass of the vehicle. The road being wet will reduce the coefficient of friction of the road surface/tyre boundary compared to when the road surface is dry. It is easier, by experiment, to do a few test runs using a vehicle of similar mass under similar conditions to get how the vehicle is likely to have slowed down when it skidded, and extrapolate/interpolate to the given distance of 24.2 m.
