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
What is the acceleration of a car that moves at a steady velocity of 100 kmh for 100 seconds Explain your answer and state why this question is an exercise in careful reading as well as in physics?
Acceleration = 0 because the car is moving at a STEADY velocity. It is neither speeding up, nor slowing down.
What is the decrease in magnitude of velocity called?
It is called deceleration or slowing down.
What type of acceleration do you have if you are slowing down?
If you are slowing down, you have negative acceleration, which is commonly referred to as deceleration. Deceleration represents a decrease in velocity over time.
What is a decrease in the magnitude of velocity called?
It is called deceleration or slowing down.
How do you calculate deceleration on a velocity time graph?
Deceleration on a velocity-time graph is calculated by finding the slope of the line segment representing the decrease in velocity. The formula for deceleration is given by the change in velocity divided by the time taken for the velocity to change. It indicates how quickly the object is slowing down.
What kind of acceleration is occurring if an object is slowing down?
If an object is slowing down, it is experiencing negative acceleration, also referred to as deceleration. This means that the object's velocity is decreasing over time.
Can anything have an acceleration in the opposite diretion to its velocity?
Yes. If an object is slowing down, its acceleration would be in the opposite direction to its velocity. This situation is common when an object is experiencing deceleration or braking.
What is the scientific term for slowing down?
The scientific term for slowing down is deceleration. It refers to the decrease in speed or velocity of an object over time.
What is another word for acceleration while slowing down?
Deceleration is another word for acceleration while slowing down. It refers to the rate at which an object's velocity decreases over time.
Two words for what happens when an objects velocity decreases?
negative acceleration
When velocity decreases this could be referred by?
When velocity decreases, it can be referred to as deceleration or negative acceleration. This means that the rate at which an object is moving is slowing down.
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 deceleration mean negative of acceleration?
Deceleration is the negative of acceleration when the object is slowing down. However, it's important to note that deceleration is actually a type of acceleration, where the object is accelerating in the opposite direction of its initial velocity.
