Slowly press on the accelerator to go more quickly. Slowly press down on the brake pedal to go more slowly. These two operations can safely change a car's velocity.

What is a cars acceleration if it travels 0 to 55 miles per hour in 6 seconds?
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
If a car traveling at 30meters per second slows to a stop in 15 seconds what was the cars acceleration?
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
How do you find acceleration using velocity and time?
Acceleration = (change in velocity) divided by (time for the change)
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
What is the rate of change of position at a specific point in time?
The rate of change of position is the velocity. The velocity at a specific point in time is called the instantaneous velocity.
When cars are changing direction they are also changing what?
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
When a cars velocity is uniform what it is acceleration?
When a car's velocity is uniform, its acceleration is zero. This means that the car is not speeding up or slowing down, but maintaining a constant speed. Uniform velocity indicates that there is no net force acting on the car to change its motion.
What is a cars acceleration if it travels 0 to 55 miles per hour in 6 seconds?
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
What is Three ways in which a cars velocity will change?
Acceleration: When a car speeds up or slows down, its velocity changes due to an acceleration in the direction of motion. Deceleration: If the car is moving in a certain direction and slows down, its velocity decreases. Change in direction: If the car turns a corner or changes its course, its velocity changes as it moves in a different direction.
Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
What is the range of change of velocity?
The range of change of velocity is determined by the final velocity minus the initial velocity. It represents the magnitude and direction of the change in velocity of an object.
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
What is the change in velocity of an object during a period of time?
The change in velocity of an object is determined by subtracting its initial velocity from its final velocity, taking direction into account. This change can be positive (speeding up), negative (slowing down), or zero (constant velocity). The formula for change in velocity is Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
What is a change in velocity in given period of time?
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
How does a change in speed change velocity?
due to acceleration the speed and velocity will change automatically
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
