It has been suggested that deceleration ability is underpinned by four major NMP qualities, namely dynamic balance, eccentric strength, reactive strength and power [11] .

4. Before you move, check for traffic in rearview and sideview mirrors.
5. Turn on your directional signal to indicate the direction you plan to move.

What is the key to smooth stopping? Looking for enough ahead to begin slowing early, ease up on the accelerator, apply the brake gently at first, then increase pressure gradually as car is slowing as much as desired, ease up on the brake before coming to a stop.

Deceleration is the opposite of acceleration. The deceleration will be computed by dividing the final velocity minus the initial velocity, by the amount of time is taken for this drop in velocity.

“Retardation means negative acceleration. So formula will be the same as that of acceleration. As acceleration can be defined as the rate of change of velocity i.e. mathematically: a= (v-u)/t. Where v = final velocity, u= initial velocity & t= time taken to change the velocities.

Stopping distance = reaction distance + braking distance.

Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous.

Acceleration is defined as the rate of change of velocity. For a particular interval, the average acceleration is defined as the change in velocity for that particular interval. Unlike acceleration, the average acceleration is calculated for a given interval.

Average acceleration, ¯a is defined as the rate of change of velocity, or the change in velocity per unit time. The units of acceleration are distance over time squared. A symbol with a bar over it is read as average – so a-bar is average acceleration.

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

6m/s2.

Acceleration is defined as the rate of change of velocity and is an example of a vector quantity. Uniform acceleration: When an object is travelling in a straight line with an increase in velocity at equal intervals of time, then the object is said to be in uniform acceleration.

There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

A positive acceleration means an increase in velocity with time. negative acceleration means the speed reduces with time. When the car slows down, the speed decreases. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

Positive acceleration is an increasing speed or increasing magnitude of velocity of moving body. For example, 1)An aeroplane accelerating for take off. 2) Accelerating a car to increase its speed.

The linear motion can be of two types: uniform linear motion with constant velocity or zero acceleration; and non-uniform linear motion with variable velocity or non-zero acceleration.

An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. The final motion characteristic for an object undergoing uniform circular motion is the net force.

centripetal force

Isaac Newton built on Galileo’s thoughts about motion. Newton’s first law of motion declares that a force is not needed to keep an object in motion. Slide a book across a table and watch it slide to a rest position. A force is not required to keep a moving book in motion.

Is an external force required to keep a body in uniform motion? The simple and sweet answer would be NO. This implies that in the absence of an external opposing force, a body in motion will be in uniform motion forever.

during its downward motion. 3. at the highest point where it is momentarily at rest.
