## What data should you collect to calculate speed?

For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is. Same calculation.

## Can speed be calculated?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

## How is v average calculated?

The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.

## Can you tell from a displacement-time graph whether an object is stationary?

Can you tell from a displacement-time graph whether an object is stationary? Yes. If the object is stationary, it will appear as a horizontal line on a displacement-time graph.

## What does the area under force displacement graph represent?

The area under force displacement curve represents work done. Explanation: The area under the force displacement curve represents the work done. It is the distance (s) of the object displaced by the application of the force (f).

## How can you find out work from force-displacement curve?

If we plot the force, F, acting on an object (y-axis) by the distance moved, s, (x-axis) we make a force-displacement graph. These are useful because we can always find the work done by (or on) a system by finding the area under a force-displacement graph.

## When angle between force and displacement lies between & Work will be?

The angle between force and displacement should be θ = 90° for minimum work. The angle between force and displacement should be θ = 0° for maximum work.

## When angle between force and displacement lies between 90 & 180 work will be?

Since the angle between the force and displacement is 180 degrees, the work done by the gravitational force on the body is negative.

90°

180°

## How is an angle of Measure 1 degree formed?

In this method, we measure an angle in terms of degrees, minutes and seconds. We divide the circumference of a circle into 360 equal arcs. The angle subtended at the centre of the circle by one arc is called one degree and is denoted be 1∘(The small circle is a symbol for degree).

## Can you have negative angles?

An angle is a measure of rotation. Angles are measured in degrees. One complete rotation is measured as 360°. Angle measure can be positive or negative, depending on the direction of rotation.

## Are negative angles clockwise?

In other words: the positive angles are counterclockwise, the negative angles are clockwise.

## What is 0 degree angle called?

An angle equal to 0° or not turned is called a zero angle. Angles smaller than a right angle (less than 90°) are called acute angles (“acute” meaning “sharp”).

## How do you know if an angle is positive or negative?

Positive and Negative Angles The measure of an angle describes the magnitude and direction of the rotation of the ray from its initial position to its terminal position. If the rotation is counterclockwise, the angle has a positive measure. If the rotation is clockwise, the angle has a negative measure.

## What happens when an angle is negative?

Same distance, different directions. a positive angle starts from an initial side and moves clockwise to its terminal side. A negative angle starts from an initial side and moves counterclockwise to its terminal side.

## What is standard position in math?

: the position of an angle with its vertex at the origin of a rectangular-coordinate system and its initial side coinciding with the positive x-axis.

## Is clockwise on or off?

Clockwise means moving in the direction of the hands on a clock. Imagine you walk around something and always keep it on your right. Most screws and bolts are tightened, and faucets/taps are closed, by turning clockwise.
