Acceleration is defined as the rate of change of velocity with respect to time. It is a vector quantity, meaning it has both magnitude (how quickly speed is changing) and direction (the direction in which the speed is changing). Formally, acceleration (a) can be expressed as a = (v_f - v_i)/t, where v_f is the final velocity, v_i is the initial velocity, and t is the time interval over which the change occurs.

Can a car driving backwards have a positive acceleration?
Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
How do scientists define mass?
Scientists define mass as the measure of the amount of matter in an object. It is a fundamental property of an object that remains constant regardless of its location in the universe. Mass is typically measured in kilograms or grams.
What are two components used to define motion?
Velocity and acceleration are two components used to define motion. Velocity describes the speed and direction of an object's motion, while acceleration describes how quickly an object's velocity is changing.
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 do scientists define energy as?
Scientists define energy as the ability to do work or cause a change. It can exist in various forms such as kinetic, potential, thermal, or electromagnetic energy. Energy cannot be created or destroyed, but only transformed from one form to another.
How does scientists define matter?
Scientists define matter as anything that has mass and takes up space. Matter is composed of atoms, which are the basic building blocks of all substances. It exists in various states, such as solid, liquid, and gas.
How do scientists define when work occurs?
they define when work occurs energy. Energy is the ability to do work.
How can you define acceleration due to gravity?
yes, 9.81 m/s^2
