How do you solve for the rate of change in algebra?
The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:d=rt, then to solve for r we divide both sides by t and have d/t=rIn mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.
What is an example of a negative rate of change?

What is an example of a positive rate of change?
a car going from stoplight to next intersection accelerates at a positive rate of velocity change
Quadratic equation in real life?
One example... X = 1/2 A t2 + V0 t + X0 Where X is distance, A is acceleration, t is time, V0 is initial velocity, and X0 is initial distance. This allows you to calculate where you would be given a starting position, velocity, and acceleration, after a specified time, such as in an automobile.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
What MUST be true about an object's acceleration as it is traveling in the positive direction and slowing down?
The object's acceleration must be in the negative direction, opposing its velocity in the positive direction. This negative acceleration is also known as deceleration and causes the object to slow down.
Differentiate positive acceleration and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration occurs when an object's velocity is decreasing. Positive acceleration is associated with motion in the direction of velocity, while negative acceleration usually indicates motion in the opposite direction of velocity.
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
Does acceleration have a negative or positive value if the velocity is increasing speed?
Acceleration has a positive value if the velocity is increasing speed. Positive acceleration means the object is speeding up.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
How can you tell if acceleration is positive or negative?
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
When your slowing down is your acceleration positive or negative?
When you are slowing down, your acceleration is negative. This is because acceleration is the rate of change of velocity, and when you are slowing down, your velocity is decreasing. A negative acceleration indicates a decrease in velocity in the given direction.
How is a negative acceleration different from a positive acceleration?
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
Does a softball have a positive or negative acceleration when it is thrown?
When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
What is the effect on accelerationif we decreasing velocity?
If velocity is decreasing, acceleration is in the opposite direction of the initial velocity. If the velocity is decreasing at a constant rate, the acceleration is negative, causing deceleration. If the velocity is decreasing while changing direction, the acceleration may be a combination of negative and positive components.
