If a body starts from rest what can be said about the acceleration of body?
If a body starts from rest, it means its initial velocity is zero. In this case, if the body is in motion, it has undergone acceleration to reach that velocity. Therefore, the acceleration of the body must be non-zero, indicating a change in velocity over time.
Distinguish between velocity and acceration. Use an example to demonstrate your answer?
Velocity is the rate of change of displacement with respect to time, while acceleration is the rate of change of velocity with respect to time. For example, a car moving at a velocity of 50 km/h increases its velocity to 70 km/h in 5 seconds. The car experienced acceleration during this time period.
What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
What is the skydiver velocity aftter one second show your work and include direction?
Assuming the skydiver starts at rest and accelerates at a rate of 9.8 m/s^2 due to gravity, the velocity after one second would be 9.8 m/s downward. This is because velocity is the initial velocity of 0 m/s plus the acceleration of 9.8 m/s^2 multiplied by 1 second.
What path might an object take that involves changing the velocity?
An object might change its velocity by accelerating, decelerating, changing direction, or a combination of these. For example, if a car starts from rest and accelerates along a straight road, it would experience a change in velocity. Another example is a ball thrown upwards experiencing a change in velocity as it goes up and then down due to the acceleration of gravity.
A car starts from rest and travels a distance of 100 m in 20 seconds with a constant acceleration The velocity of the car is at the end of the 20 second interval is?
velocity=5 meters/sec Velocity=change in distance/change in time velocity=m/s change in distance=meters change in time=sec v=x/t v=100m/20s v=5m/s
What is the acceleration of an object that starts stopped and after 5 seconds is going 25mm per hour?
the acceleration is increasing speed Acceleration = velocity change / time velocity change = 0 to 25 mm/hr = 25 mm/hr time = 5 seconds therefore acceleration = 25/5 mm/hr per second = 5 mm per hour per second.

If an object moved with constant acceleration it's velocity must ?

Can you describe how velocity changes during free fall?
Yes I can! I shall now do so, ignoring the effects of air resistance: During free fall, the direction of motion doesn't change. But the speed increases, steadily and continuously. The amount by which the speed increases each second is called the "acceleration of gravity". On earth, the speed is 9.8 meters per second (32.2 ft per second) greater after each second of free fall.
What is the velocity of a ball thrown upward at 16 feet and seconds?
The initial velocity of the ball is 16 feet per second when thrown upward. The velocity decreases as the ball travels upward due to gravity until it reaches its peak and starts to fall back down.
What is the definition of final velocity?
Final velocity is the your last velocity traveled. Example if you travel 50m/s your final velocity is 50m/s because its the last velocity traveled, 0m/s is the initial velocity. Its not your total velocity because if u start running at 5m/s then accelerated 25m/s, your final velocity is NOT 30m/s. It is 25m/s. Also, your velocity change is 20m/s(25-5).
What is the rate at which an object changes velocity is called?
It is acceleration. Recall the accelerator hold in case of two wheeler and accelerator pedal in case of four wheeler. After the engine is started then we turn the throttle and vehicle starts moving from rest and soon the velocity goes on increasing. The more we turn in case of two wheeler and the more we press the pedal in case of four wheeler, the speed gets increased so quickly. So 'rate of' phrase is used to mean any change with respect to time or change happening in one second. Rate of displacement is velocity Rate of change in velocity is acceleration Rate of doing work is power Rate of flow of charge is electric current.
