A straight line with a constant slope.
But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
Position-Time GraphYou can graph motion on a position vs time graph. On a position vs time graph, position is on the y-axis and time is on the x-axis. If the velocity is constant, the graph will be a straight line and the slope is average velocity. If the motion is accelerating, the graph will be a curved line.Velocity-Time GraphYou can also graph motion on a Velocity-Time graph. On a velocity vs time graph, velocity is on the y-axis, time is on the x-axis. If the graph is a straight line, velocity is constant and the slope is average acceleration. Also, on a velocity vs time graph, the area under the line is displacement.Refer to the related link for illustrations of the different graphs of motion and their meanings.
The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In the case of an ice skater sliding across the ice at a constant velocity, the skater will continue moving at that constant velocity unless a force (like friction or wind resistance) acts to change their motion.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.
On a velocity-time graph, constant velocity motion is characterized by a horizontal line where the velocity remains the same over time. The slope of the line is zero, indicating that the acceleration is zero and the object is moving at a steady speed.
For uniform motion, the position-time graph will be a straight line with a constant slope, indicating a constant velocity.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
When the slope of a position vs. time graph is constant, it indicates that the object is moving at a constant velocity. This type of motion is called uniform motion, where the object covers equal distances in equal intervals of time.
No, the velocity is not constant for an object in uniform circular motion because the direction of the velocity is changing continuously due to the object's changing direction as it moves along the circular path. The magnitude of the velocity (speed) remains constant, but the velocity vector is constantly changing direction.
No. The definition of acceleration is change in velocity.
Well, we know that velocity describes the speed and direction of motion, so you can't change either of those. We don't usually think of 'position' as a characteristic of motion, but if we try hard to please you, then we might observe that the position changes while velocity remains constant.
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
It is motion in a straight line at a constant velocity.
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
It is called uniform motion because the object covers equal distances in equal intervals of time which is why it has a constant velocity.
