As the car moves down the street, the velocity is positive. As it comes to a red light and stops, the velocity decreases to zero. Waiting at the red light, the acceleration is zero. When the light turns green and the car accelerates, the velocity increases from zero to a positive value, and the acceleration is positive.
What else can I help you with?
Suppose that you are running down the street at 6 msec. You see your dog ahead and speed up to 10 msec over 20 sec to catch him. What is your acceleration in ms2?
Your initial velocity is 6 m/s, and your final velocity is 10 m/s. The total change in velocity is 4 m/s (10 m/s - 6 m/s). Given that this change occurs over 20 seconds, you can calculate the acceleration using the formula acceleration = change in velocity / time. Therefore, the acceleration is 0.2 m/s^2.
Is speed different from acceleration?
Acceleration is the change of velocity while Velocity is the rate of change of displacement (position).I-Edison of RSHS IX '10-'11
Ben runs from a position 3 m wesr of main street to a new position 45 m west of main street in 6 seconds what is ben's velocity?
Ben's velocity can be calculated using the formula velocity = displacement / time. In this case, Ben's displacement is 45 m - 3 m = 42 m (since he ran from 3 m to 45 m west). Thus, his velocity is 42 m / 6 s = 7 m/s west.
What is meant by the statement rest and motion are relative terms give example to show it?
The statement "rest and motion are relative terms" means that whether an object is considered at rest or in motion depends on the observer's frame of reference. For example, a person sitting on a bus is at rest relative to the bus, but in motion relative to a person standing on the street. This illustrates that rest and motion are relative concepts.
Does motion have to be measured relative to a frame of reference?
Because motion only exists relative to something else. when measured from different reference frames, the same motion will appear to have different speeds, accelerations, and directions. And the thing of it is ... they'll all be correct !
If Ben runs from a position 3 miles west of Main Street to a new position 45m west of Main Street in 6 seconds - What is Ben's velocity?
Velocity = distance divided by time / Velocity = average speed over time / Acceleration = (change of) velocity divided by time elapsed Change in velocity = final velocity "minus" initial velocity divided by time elapsed
Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?
An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.
Suppose that you are running down the street at 6 msec. You see your dog ahead and speed up to 10 msec over 20 sec to catch him. What is your acceleration in ms2?
Your initial velocity is 6 m/s, and your final velocity is 10 m/s. The total change in velocity is 4 m/s (10 m/s - 6 m/s). Given that this change occurs over 20 seconds, you can calculate the acceleration using the formula acceleration = change in velocity / time. Therefore, the acceleration is 0.2 m/s^2.
What if your walking down the street describe the forces acting on you and use Newton's laws of motion to describe your motion?
When walking down the street, the two main forces acting on you are gravity pulling you down towards the Earth and the normal force from the ground pushing you up. According to Newton's first law of motion, if the forces are balanced (in this case, gravity and the normal force), you will continue moving at a constant velocity in a straight line. If you want to change your motion (speed up, slow down, change direction), you would need to apply an additional force in the direction you want to move.
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant

What is a summary of street cries summary?
Describe the summary of street criesby sarojini neidu
How does the narrator describe the street at the beginning of the story?
Quiet
How are force and motion?
In order to create force, you have to create motion. So if you were to push on a box or pull your child away from the street, you would be creating a motion and force.
How do you find the distance time and velocity if you only have the acceleration?
you cannot. you can find roughly the average by cubic routing it. If you only have the acceleration, then you only have the acceleration, and no matter how you massage it, there's no way to tease anything else out of it without some more information. Here's the question you're asking: "I left my house, pulled out of the driveway, turned onto the street, put the pedal to the metal, and started accelerating at the rate of 360 miles per hour2. How far did I go, how soon did I get there, and when I arrived, what was my speed and what direction was I headed ?"
A car as it turns right at a street intersection engages in circular motion?
True
How does the narrator describe his street at the beginning Araby the story?
Loud quiet
