how do u calculate the displacement?
3935
To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.

['Horizontal distance traveled can be expressed as x = Vx * t , where t is the time.', 'Vertical distance from the ground is described by the formula y = h + Vy * t – g * t² / 2 , where g is the gravity acceleration.']

It cannot be greater than the magnitude of the distance travelled by an object, but it can be smaller than the magnitude of the distance travelled by an object or , it may be equal to the distance travelled by the object. (a) is not true. Displacement can be zero.

Use the equation y = 0.5 • g • t2 and substitute -9.8 m/s/s for g. The vertical displacement must then be subtracted from the initial height of 78.

If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length. In that case, the magnitude of the average velocity is equal to the average speed.

Displacement is a vector quantity i.e. it possess both a magnitude and a direction. On the other hand, it's magnitude is just a scalar quantity. For example, if you move 5 metres north, '5 metres' is the magnitude of your displacement, and '5 metres north' is the displacement.

We can write this principle in equation form as: FB = ρf Vf g. where FB is the buoyant force, ρf is the density of the displaced fluid, Vf is the volume of the displaced fluid, and g is the acceleration due to gravity, 9.8 m/s2.

Displacement is the distance moved in a straight line, in a given direction, from the starting point. Displacement is a vector quantity as it has size and direction.

Displacement is the vector difference between the ending and starting positions of an object. Velocity is the rate at which displacement changes with time. It is a vector, too. The average velocity over some interval is the total displacement during that interval, divided by the time.

Displacement is the change in position of an object or person, measured in meters. ... And acceleration is the rate at which your velocity is changing, measured in meters per second per second (or meters per second squared).

The two quantities are equal when the motion occurs without any change in direction. In that case, the individual displacements point in the same direction, so the magnitude of the net displacement is equal to the sum of the magnitudes of the individual displacements (the total distance).

Its length corresponds to the magnitude, or size, of the movement, and the arrow points in the direction of travel. This makes displacement a vector quantity because it incorporates both movement, magnitude and direction. In the shorthand of physics, displacement is written as Δs.

What the equation and illustration below demonstrates is that linear displacement of any point on a rotating body is proportional to the radius of rotation (r; distance that point is from axis of rotation) and the angular displacement of the rotating body.

The phase relationship between displacement, velocity, and acceleration is that such that velocity is 90° out of phase with acceleration and displacement is 180° out of phase with acceleration. In other words, when displacement is at a maximum, velocity is at a minimum, and acceleration is at a maximum.

The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg. The weight of an object or substance can be measured by floating a sufficiently buoyant receptacle in the cylinder and noting the water level.

Displacement is a vector which points from the initial position of an object to its final position. The standard units of displacement are meters. Velocity is a vector which shows the direction and rate of motion. ... Acceleration is a vector which shows the direction and magnitude of changes in velocity.

The first of these, the Displacement-Length Ratio (D/L) is a nondimensional expression of how heavy a boat is relative to its waterline length. A D/L ratio is calculated by dividing a boat's displacement in long tons (2,240 pounds) by one one-hundredth of the waterline length (in feet) cubed.
