Can the velocity of a particle change even if its speed is constant give examples?
Give example. Yes. Even though its speed is constant, if it is not traveling in a straight line, the velocity can vary.
Can an object have zero velocity but non zero acceleration?
Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.
Can a moving object have speed but no velocity and vice versa?
While the speed can remain the same. So in this way, the velocity can vary and the speed can be constant. But the vice versa is never possible.
In which graph is the object moving at a constant velocity What is the velocity?
A horizontal line on the V-T graph means constant velocity.
Which object is maintaining a state of motion?
Objects A and E. Objects A and E are maintaining their state of motion. To maintain the state of motion is to keep a constant velocity (i.e., to have a zero acceleration). This translates into a zero slope on a v-t graph.
In which graph is the velocity constant?
A constant velocity means the position graph has a constant slope (of 11.11 m/s). It’s a straight line sloping up, and starting below the origin. The displacement is the area under the curve of the velocity graph.
What are the examples of constant velocity?
Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice. A space probe that is drifting through interstellar space.
What is the velocity time graph for uniform motion?
A velocity-time graph with a flat line (slope of zero) indicates uniform motion.
What is the slope of the path of a body in uniform motion?
If body moves with constant velocity then acceleration will be zero. So slope of v-t graph will be zero.
Is there any relation between the slope and acceleration?
It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
What is the slope of the path of a body when it is in uniform motion?
Slope decreases with time. When a body is moving with a uniform retardation and its initial velocity is not zero. As θ > 90°, graph has a negative slope.
Which of the following can decrease in motion in a straight line with constant acceleration?
When a body moves along a straight line with constant retardation, its speed goes on decreasing as it goes on covering less distance.
