It is the rate of change of the distance of an object in a particular direction.If a body travels a distance of S-meter in t seconds in a given direction, then, Velocity = Distance travelled in a given direction/ time taken=S/T (meters per second)

In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

Average Speed- It is defined as the total path length travelled divided by the total time interval during which the motion has taken place. Average Speed = Average Velocity- It is defined as the change in position or displacement (?x) divided by the time intervals (?t) in which the displacement occur.

The different types of velocities are uniform velocity, variable velocity, average velocity and instantaneous velocity.

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.

The formula speed = distance ÷ time can be rearranged, just like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.

Electronic speedometers. Photo: There are quite a few speedometer apps for smartphones, which calculate your speed using GPS (satellite positioning) (or other phone-location) signals (how far you’ve traveled) and the time. Android apps include GPS Speedometer and Odometer and SpeedView.

There are two types of speedometers: electronic and mechanical. Because the electronic speedometer is actually a relatively new invention — the first all-electronic speedometer didn’t appear until 1993 — this article will focus primarily on the mechanical speedometer, or the eddy-current speedometer.

A speedometer measure the speed of a vehicle in motion. Odometer records the distance travelled by the vehicle. Odometer is also used by people who construct road and survey lands. A speedometer is a gauge which tells you the velocity of the vehicle at that moment.

Good turning techniques Generally the ideal speed at the apex of a right turn is 10-15 MPH. The ideal speed in the middle of a left turn is usually 15-20 MPH.

As you begin turning the wheel, release the pressure on the brake. Through the apex of the turn, there shouldn’t be any pressure on the brake. Instead, apply light pressure to gas pedal as you come out of the turn.

You should always avoid heavy braking or accelerating while turning as this can cause your car to become unstable.

Common driving wisdom holds that you get more traction during a turn when you are accelerating. For many drivers, it’s standard practice to decelerate before entering a turn, then accelerate once they are half way through (past the apex).
