A car is moving at a constant speed is it accelerating?
This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.
When an object is thrown straight up into the air what is its acceleration when it is moving upward?
The acceleration at the top of the path will be the same as the acceleration at the moment the ball leaves the hand and all the way until the moment it hits the ground (or hand). Ignoring air resistance, the only force acting on the ball is gravity. so the acceleration is 'g' or approximately 9.81m/squared seconds in my part of the world. g depends on how close the ball is to the center of the earth.
Does mass effect the distance of objects rolling down a slope?
If you are in a real world situation there are a lot of factors to consider. In theoretical situation, ignoring friction and air drag etc, if a roller with mass m rolls down a slope to a horizontal surface it will continue rolling on the horizontal surface indefinitely. The velocity attained will be affected by the distribution of mass in the roller. If most of the mass is concentrated to a small volume that is axially located then the velocity will be different from if the mass is concentrated to the outer perimeter of the roller. In the latter case of peripheral mass concentration the acceleration will be slower but more energy will be stored as rotational inertia and in a real world situation the roller will continue rolling further.
Is it possible for an object to have acceleration and no velocity?
It's possible for an object to have velocity equals to zero at some moment and to have some acceleration (when you throw a baseball upwards with the gravitation present, the ball reaches its maximum point and then starts to come back at its maximum height its velocity is zero while acceleration equals g).
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 careers are related to physical science?
The study of electrostatics (charges at rest), electricity, motion with velocity and time and acceleration, waves, electromagnetism, magnets and general physics real world problems dealing with gravity, mechanical energy and mass.
What car has the fastest acceleration in the world?
The car with the world's fastest acceleration time from 0-60 mph or 0-100kph is the Ariel Atom V8 with a time of 2.3 seconds.
What was the situation of the world when independence of Mexico started?
The situation when the independence of Mexico started was that World War II.
How do you write an algebraic expression from a real world situation?
2*pi*sqrt(L/g) this expression gives (approximately) the period (in seconds) of a pendulum whose length is L (metres) and g is the acceleration due to gravity = 9.8 metres/second2.
What is the world record for the acceleration of a land vechile with a driver?
Its a thrust ssc
At what rate do things fall?
The speed that things fall to the earth depends on two things, how fast they started falling and how long they have been falling. The equation for finding that speed, v, is: v = v0 + a*t where v0 is the initial speed something began falling, a is the acceleration or change in velocity is causing it to fall, and t is the time it has been falling. If the object is falling on the earth, the acceleration due to gravity is 9.8 m/s2. So, if you drop something off a very tall building by just letting it go, letting v0 = 0, then after 10 seconds, it will be moving at 98 m/s. The weight of the object only matters if there is air resistance.
What is the speed of an free falling object?
Ignoring the effects of air resistance, freely falling objects accelerate at a constant rate. On Earth, the acceleration due to gravity is 9.8 meters per second squared or 32.2 feet per second squared. In the real world, however, objects don't speed up forever. Air resistance places a limit on how fast they can go.
