How do you describe a velocity-time graph?

A velocity-time graph shows the changing velocity of the sprinter or of any other moving person or object. In a velocity-time graph, acceleration is represented by the slope of the graph line. If the line slopes downward, like the line between 7 and 10 seconds, velocity is decreasing and acceleration is negative.

What does it mean when a velocity-time graph is straight?

What does a straight line down mean on a velocity time graph? On a velocity-time graph a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object’s velocity is changing.

What words describe velocity?

velocity

• celerity,
• fastness,
• fleetness,
• haste,
• hurry,
• quickness,
• rapidity,
• rapidness,

How do you describe a velocity?

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north).

What would you infer if velocity-time graph is straight?

A flat horizontal line in a velocity-time graph states that the body is moving at a constant velocity. If the straight line has a slope, then that indicates the body is changing its velocity at a constant rate, or it means that the body has constant acceleration.

What is it called when a graph is straight?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear. y.

What’s another word for velocity?

Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object.

What can velocity tell you?

The instantaneous speed of an object is then the magnitude of its instantaneous velocity. Speed tells you how fast. Velocity tells you how fast and in what direction.

Does velocity mean speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.

What is a good sentence for velocity?

Velocity sentence example. The other forms of velocity anemometer may be described as belonging to the windmill type. After Professor Amund Helfand had, in July 1875, discovered the amazingly great velocity , up to 644 ft.

How do you describe the trend of a graph?

Describing language of a graph

• UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
• DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
• UP & DOWN: fluctuate / undulated / dip /
• SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.

What is an acceleration vs time graph?

When the slope of the line is positive, the acceleration is speeding up in a positive direction. When the slope of the line is negative, the object is decelerating. An acceleration time graph is particularly useful when trying to find the total distance traveled by the object.

What is the formula for velocity?

In simple words, velocity is a measure of how much time an object takes to reach a destination with direction. Moreover, it is directly related to displacement and inversely relates to the time traveled. Also, its unit is meter per second (m/s). Velocity formula = displacement ÷ time

What is the slope of velocity time graph?

What does the slope of velocity time graph represent? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant. Can you draw a graph for uniform motion?

What are position vs. time graphs?

An x vs. t graph (position vs. time graph) is a picture of how these certain positions match up with the certain times. Using the above data table, the information looks like this on a position vs. time graph: The time axis is horizontal, the position axis is vertical.
