A motorcycle slows down from 40 ms to 20 ms If this takes 4 seconds what is the motorcycle's acceleration?
Acceleration(a) = [final velocity(v) - initial velocity(u)] / time(s) Algebrtaically a = [ v - u ] / s A negative result indicates deceleration a = [20 - 40 ]= / 4 a = [-20] / 4 a = -5 m/s^(2) This is negative which matches the question of slowing down/deceleration.
Scooter acquires a velocity of 36 kilometre per hour in 10 seconds after the start it takes 20 seconds to stop calculate the acceleration?
To find the acceleration, we need to first convert the velocity from kilometers per hour to meters per second. 36 kilometers per hour is equivalent to 10 meters per second. Next, we can use the formula for acceleration: acceleration (a) = change in velocity (Δv) / time taken (Δt). For the acceleration during the start, the change in velocity is 10 m/s (initial velocity was 0) and the time taken is 10 seconds. Thus, the acceleration is 1 m/s^2. For the deceleration (when stopping), the change in velocity is -10 m/s (final velocity was 0) and the time taken is 20 seconds. Thus, the acceleration is -0.5 m/s^2. Negative sign indicates deceleration.
How do you measure or calculate deceleration during a collision?
In a controlled test condition (like crash tests on cars) an accelerometer is used to measure the rate of deceleration. It should be possible to estimate the deceleration following a collision if the speed of the vehicles at the moment of the collision is known. We could do this by measuring the amount the car was crushed/dented during the collision. We know the vehicle decelerated from its starting speed over this distance so we can estimate the average deceleration. I believe there are more sophisticated techniques used by accident investigators. As an aside, in strict physics terminology, slowing down (as well as any other change in velocity) is acceleration, not deceleration however deceleration is often used to imply a reduction in speed in every day English. If you want to get into this further have a look at "Are speed and velocity the same?" and remember that acceleration is also a vector.
What has the greater deceleration a bicycle slowing from 3 m s to a stop in 6 second or a car slowing from 20 m s to 15m s in 6 seconds?
The car has a greater change of speed in the same period of time. So the magnitude of its acceleration is greater than the bike's is.`1111111111111111111111111111`1 decel = CHANGE in velocity divided by time in first case decel = 3/6 = .50 in second decel = 5/6 = 0.83 so second case is faster decel
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
What is a decrease in the magnitude of velocity called?
It is called deceleration or slowing down.
What is the decrease in magnitude of velocity called?
It is called deceleration or slowing down.
What is deceleration in physics?
'Acceleration' is defined as the rate of change in velocity and the direction of the change. 'Deceleration' is a popular but unscientific word used to describe acceleration with a negative magnitude, i.e. 'slowing down' without regard for its direction.
What is another word for deceleration?
Technically, it is acceleration either way. If something is slowing down, the acceleration is negative. Slow down or Decrease velocity
Is an object that is slowing down accelerating?
Acceleration is defined as change of velocity so the answer to the question is yes. Negative acceleration (ie when velocity is decreasing) is called deceleration.
What does it mean when the change in velocity is negative?
It means deceleration or slowing down and there is a force operating against the motion.
The term deceleration means?
slowing down.
What is rate of deceleration?
The rate of deceleration is how quickly something is slowing down.
Deceleration is the rate of?
slowing down
A motorcycle slows down from 40 ms to 20 ms If this takes 4 seconds what is the motorcycle's acceleration?
Acceleration(a) = [final velocity(v) - initial velocity(u)] / time(s) Algebrtaically a = [ v - u ] / s A negative result indicates deceleration a = [20 - 40 ]= / 4 a = [-20] / 4 a = -5 m/s^(2) This is negative which matches the question of slowing down/deceleration.
An object slowing down has a what acceleration?
Deceleration
Can an object have an eastward velocity while experiencing a westward accelerations?
The answer is yes and no.Acceleration is the rate of change of velocity. Velocity is speed plus direction.If an object is travelling eastward and slowing down in a straight line then its velocity is decreasing, it is still travelling eastward. However the force slowing the object is a westward force.A reducing acceleration (slowing down) is most often called a deceleration or negative acceleration. So you have a negative eastward acceleration.
