In physics what is variable acceleration and please give at least two examples of it?
Variable acceleration refers to an object's velocity changing by different amounts over time. This means that the object's speed is not changing at a constant rate. An example of variable acceleration is a car speeding up as it merges onto a highway, where the acceleration is increasing. Another example is a rocket slowing down as it enters the atmosphere due to air resistance, where the acceleration is decreasing.
Is acceleration the change in distance over time?
acceleration is the change in speed in a certain amount of time eg a car goes from 4km/h to 10km/h in 3 seconds, what is its acceleration? 10km/h - 4km/h=6 6/3 secounds=2 acceleration is 2km/h acceleration= change in speed/time
What is the acceleration of a car that screeches to a stop if it takes 3 seconds to go from 36 meters per seconds to 0 meters per seconds?
Acceleration = (change in speed) divided by (time for the change) = (0 - 36)/3 = -12 m/s2The acceleration of gravity is 9.8 m/s2, so the passengers are pulled forwardagainst their seat belts with a 'force' of 1.22 Gs during the screech.
How will acceleration change if the mass being accelerated is multiplied by three but the net force ir reduced to half?
One sixth of the original : Force = (mass) x (acceleration). So Acceleration = (Force)/(mass).So A1 = F1/m1 ; if F2 = .5*F1 and m2 = 3*m1. So A2 = F2/m2 = (.5*F1)/(3*m1) = (F1/m1)/6 = A1/6.
Explain why an object cannot keep accelerating?
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
What are acceleration examples?
Examples of acceleration are change in speed, change in direction, or both.
What are some examples of acceleration questions that can be used to assess students' understanding of the concept of acceleration?
Some examples of acceleration questions that can be used to assess students' understanding of the concept include: What is the formula for calculating acceleration? How does acceleration differ from velocity? Can an object have acceleration if its speed is constant? Explain. Describe a scenario where an object experiences positive acceleration. How does mass affect an object's acceleration when the same force is applied?
Are not examples of centripetal acceleration Check all that apply.?
Examples of centripetal acceleration include a car turning a corner, a ball moving in a circular path on a string, and a planet orbiting around a star.
Give examples of derived quantities?
work,velocity,force and acceleration
Examples for acceleration?
speeding of car speeding of a free falling object.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
Is increasing acceleration the same as positive acceleration?
Yes, increasing acceleration means that the rate of change of velocity is increasing, which implies positive acceleration. Positive acceleration corresponds to speeding up, while negative acceleration (deceleration) corresponds to slowing down.
What are the two examples of motion in which the instantaneous speed changes?
Acceleration and deceleration are two examples of motion in which the instantaneous speed changes. Acceleration occurs when an object speeds up, while deceleration occurs when an object slows down.
What is the acceleration of a 3 kg mass if a force of 14.4 N is used to move the mass?
Acceleration = force/mass:14.4 / 3 = acceleration of 4.8meters per second squared.
What are the examples of vector?
Examples of vector quantity are displacement, velocity, acceleration, momentum, force, E-filed, B-field, torque, energy, etc.
A car accelerates to pass a truck going from 20 ms to 29 ms in 3 seconds what was the acceleration.?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substituting the values: acceleration = (29 m/s - 20 m/s) / 3 s = 3 m/s^2. Therefore, the acceleration of the car was 3 m/s^2.
How could you keep an object acceleration the same if the force acting on object were doubled?
force = mass * acceleration if force is doubled, mass needs to be doubled to keep the same acceleration example: force = 6 mass = 2 acceleration = 3 6 = 2 * 3 12 = m * 3 12/3 = m 4 = mass
