I suggest a 3-dimensional star shape, each of whose faces are not plane but concave.
The bottom of the wheels.
moving a point or shape etc a distance in a certain direction
No, they are not the same! Velocity involves the speed and the direction of the moving object...
right is defined as the positive direction
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
The force of gravity is always in the same direction ... toward the center of mass of the other mass that's involved ... whether or not the body is in motion, regardless of what direction it may be moving, and regardless of whether or not you throw up.
aerodynamic |ˌe(ə)rōdīˈnamik|adjectiveof or relating to aerodynamics : aerodynamic forces.• of or having a shape that reduces the drag from air moving past : the plane has a more aerodynamic shape.
That would depend on which direction u r facing as it moves left across your field of view. If u r facing West, the spicemen would b moving south, if u r facing north, it would b moving west, if u r facing east, it would b moving north, & if u r facing south, it would b moving east. Most likely the specimen would b travelling in a frontwards direction as opposed 2 backwards, but I think most live specimens r able 2 move in either direction (except maybe fish?) LOL! But im not sure of that fact.
aerodynamic or streamlined
Speed is a scalar quantity that measures how fast an object is moving, regardless of direction. Velocity, on the other hand, is a vector quantity that includes both the speed of an object and the direction in which it is moving. So, while speed tells you how fast an object is moving, velocity tells you both how fast and in what direction it is moving.
Speed and velocity both describe how fast an object is moving. The main difference is that velocity includes direction, whereas speed is just a measure of how fast something is moving regardless of direction.
Velocity is a vector quantity that includes both speed and direction, so it measures how fast an object is moving in a specific direction. Speed, on the other hand, is a scalar quantity that only measures how fast an object is moving regardless of direction.
The resistance that results when a body moving through the air is called aerodynamic drag or air resistance. It is a force that acts opposite to the direction of motion, slowing down the movement of the object.
No, speed does not include the direction an object is traveling. Speed only refers to how fast an object is moving regardless of its direction. Velocity, on the other hand, includes both speed and direction.
distance covered by the object per unit time is the speed of the object.
Velocity tells you the speed of an object in a specific direction, while speed only tells you the how fast it is moving regardless of direction. Velocity is a vector quantity, combining speed with direction, whereas speed is a scalar quantity.
why are the triangles and semi circles on the symbol for a cold front and a warm front facing in one direction The symbols are on the side in which the front is moving. If it is stationary then it alternates.
