What is the relationship between accerleration and velocity?
Acceleration is the rate of change of velocity over time. When an object experiences acceleration, its velocity changes either in magnitude, direction, or both. If acceleration is positive, the object's velocity is increasing; if acceleration is negative, the object's velocity is decreasing.
True or false a negative slope on the velocity vs. time graph indicates that the object is not accelerating?
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.
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.
Do Both speed and acceleration include the direction of an object's motion?
No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."
What is the physics definition for acceleration?
Acceleration is the rate of change of velocity of an object over time. It is a vector quantity that indicates both the magnitude and direction of how an object's velocity is changing. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity).

Explain the difference between acceleration and deceleration?
When an object is moving with different velocity with respect to time then the object is in acceleration or decceleration mode. If the rate of change of velocity is positive then it is said to be accelerated, if its negative it is said to be deaccelerated.
What is the objects acceleration?
The acceleration of an object is the rate at which its velocity is changing over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration can be positive, negative, or zero, depending on whether the object is speeding up, slowing down, or maintaining a constant velocity.
What is deceleration in physics?
Deceleration in physics refers to the rate at which an object slows down its speed or velocity. It is the negative acceleration of an object moving in the opposite direction of its velocity vector, causing it to decrease its speed. Deceleration can occur due to various factors such as friction, air resistance, or external forces acting on the object.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.
The ability to apply a change in velocity on a given object.?
The ability to apply a change in velocity on an object is known as acceleration. Acceleration can be positive (speeding up), negative (slowing down), or changing direction. It is a vector quantity with both magnitude and direction.
What indicates the acceleration of an object?
The acceleration of an object is indicated by a change in its velocity over time. If an object is speeding up, slowing down, or changing direction, it is experiencing acceleration. Acceleration is a vector quantity, meaning it has both magnitude and direction.
What is Rate of change of velocity of an object?
The generic term for change in velocity is acceleration. It may be positive or negative (often called deceleration in non-scientific use) or may be a change in vector (direction of travel). This is because velocity is speed (distance covered per time unit) and direction of travel combined.
