of Accelerate
Acceleration is defined as the rate of change of velocity. When at a steady speed, there is no rate of change of velocity and therefore acceleration is zero. When the rate of change of speed is positive, such as a car speeding up, acceleration is positive. If the rate of change of speed is negative, such as a driver applying the brakes, there is negative acceleration, or deceleration.
A flammable material used to start and spread a fire in cases of arson. Petrol and paraffin are the substances commonly used.
A change in speed or direction is caused by a force and is called acceleration.
Acceleration
Acceleration is 0.25m/s2 (A = force/mass).
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
The falling motion of the broom is the acceleration of the broom The broom hitting the floor and slowing down is the deceleration of the broom. Remember, acceleration is the speeding up and deceleration is the slowing down (De is the Latin root meaning down, so down in speed/ decreasing in speed...)
acceleration is the rate of change of velocity of an object with respect to time.
acceleration
The process of speeding up
Zero acceleration means no change in velocity and no force on the zero accelerating body.
A plane landing is a negative acceleration - "negative" meaning it slows down.
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.

The Law of Inertia means , No force, No Acceleration (change in velocity) and Vice verso No acceleration (change in velocity), No Force.
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
Definition: Acceleration is the rate of change of velocity as a function of time. It is vector. In calculus terms, acceleration is the second derivative of position with respect to time or, alternately, the first derivative of the velocity with respect to time.
A change in speed or direction is caused by a force and is called acceleration.
The negative part in negative acceleration is indicating direction, as acceleration is a vector quantity. Speed however, is a scalar and has magnitude only and therefore cannot be negative. An example could be -2.6ms-2 meaning that there is an acceleration of 2.6ms-2 but in the opposite direction to other vectors.
