By using an Arrow (VECTOR) to represent its SPEED and DIRECTION. Where the Arrow points is its Direction of Motion, and its LENGTH (magnitude) is its SPEED.
In simple motion can be described as the movement of any object.
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well. Hope this helps!!
Acceleration is one of the units with which motion is described. It's the rate at which the speed of an object changes, and the direction in which the speed changes.
Some of the more basic measurements of an object we can take are time and position (or distance). From these values we can calculate things (like speed and direction) that we use to describe its motion.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
When a moving object is pushed in the direction of its motion the speed of the object increases
If the speed of an object is cited and its direction of motion is also cited, we have the velocity of the object. Velocity is speed plus a direction vector.
Friction always acts in a direction opposing the motion of an object.
The speed increases. The object accellerates positively in the direction of motion.
Its speed of motion, or its direction of motion, or both, would change. In general, the change would be described as 'acceleration'.
The direction of the frictional force on a moving object is opposite the direction of motion.
this is how motion is described in terms of speed: the object moving from one point to another.
it is speed of motion and direction of motion
when an object changes its motion it is because a new force that is greater than the original force has been applied to the object and that object changes its motion unless the force is in the same direction as the original force, which would then imply that the object stays in the same direction of motion, but moves at a greater speed in that direction.
Galileo, then Newton.
If an object is in motion it has a Velocity, which is speed and direction.
the motion is in opposite direction
The exertion of a force on an object that produces motion in the direction of a force is called work.
1). Force applied to a moving object, in the direction of its motion. Speed increases, direction remains unchanged. 2). Force applied to a moving object, opposite to the direction of its motion. Speed decreases, direction remains unchanged. 3). Force applied to a moving object, in an arbitrary direction not parallel to the direction of motion. Speed and direction both change. 4). (bonus): Force applied to a moving object, force is kept exactly perpendicular to the direction of motion at every instant. Speed remains constant, path of the motion becomes circular.
This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.
