If you push an object on an incline up at force of 20N and the accleration is negative would that mean the object will start to go down or does that mean it will deacclerate to a stop.
Acceleration is the rate of change of an object's velocity over time. It is a vector quantity, meaning it has both magnitude and direction.
Acceleration can be calculated by dividing the change in velocity by the change in time. The formula for acceleration is a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Velocity is the rate of change of an object's displacement over time, while acceleration is the rate of change of an object's velocity over time. In simpler terms, velocity tells us how fast an object is moving, while acceleration tells us how quickly the velocity is changing.
Acceleration is inversely proportional to mass. This means that as mass increases, acceleration decreases, and vice versa. This is because heavier objects require more force to accelerate at the same rate as lighter objects.
Some common examples of acceleration in everyday life include a car accelerating from a stop, a roller coaster accelerating down a steep drop, and a person jumping off a diving board and accelerating towards the water. Even something as simple as dropping a ball and watching it fall is an example of acceleration due to gravity.
