When is velocity parallel to acceleration?
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
Explain the circumstances in which the velocity and acceleration of the body is parallel?
The velocity and acceleration of a body are parallel when the body is moving along a straight path with a constant speed. In this case, the velocity is constant, and since acceleration is the rate of change of velocity, it is zero. Therefore, both the velocity and acceleration vectors are parallel and pointing in the same direction.
Can a moving body have velocity and acceleration in opposite directions explain with in example?
Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, it is possible to have zero acceleration with a non-zero velocity. This occurs when the velocity is constant. On a velocity-time graph, a flat, horizontal line represents constant velocity, while a zero slope (flat line) represents zero acceleration.
Explain Why a change in velocity effects acceleration?
Acceleration is the rate of change of velocity over time. Therefore, when there is a change in velocity, it directly affects acceleration because acceleration is influenced by how quickly or slowly an object's velocity changes. If an object speeds up, slows down, or changes direction, its velocity changes, leading to a corresponding change in acceleration.
How is newton related to acceleration and velocity?
Newton's second law of motion mathematically relates acceleration to force as F = ma, where F is the force applied to an object, m is its mass, and a is its acceleration. Acceleration is also related to velocity through the equation a = Δv/t, where Δv is the change in velocity over time t. So, Newton's laws help explain the relationship between acceleration, velocity, and force.
Explain why the slowing down of a moving object is considered to be a form of acceleration?
Acceleration is the change of velocity, with direction. Therefore slowing down is a change in veolcity, so is considered to be acceleration (just negative acceleration).
Can changing of velocity results in acceleration. Explain.?
Acceleration is change in velocity over time. a = vf - vi/Δt, where a is acceleration, vf is final velocity, vi is initial velocity, and Δt is the time interval. For example, a car accelerates from rest to 15m/s in 5.9s. What its acceleration? vi = 0m/s, vf = 27m/s, Δt = 5.9s, a = ? a = 27m/s - 0m/s/5.9s = 4.6m/s/s = 4.6m/s2
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero?
Yes, an object with zero velocity can have an acceleration that is greater than zero if there is a change in its velocity over time. Acceleration is the rate of change of velocity, so even if the object starts with zero velocity, it can still accelerate if its velocity increases or decreases.
Explain the difference between acceleration and deceleration?
Acceleration refers to an increase in speed or velocity, while deceleration refers to a decrease in speed or velocity. Acceleration can be positive (speeding up) or negative (slowing down), while deceleration is always negative. Both terms refer to changes in an object's velocity over time.
Which term explain whether an objects velocity has increased or decreased over time?
You're fishing for "acceleration", but your description doesn't support that answer.Acceleration is also present if the direction of motion has changed, even if the speed(the size of velocity) hasn't changed.Acceleration explains the change in an objects velocity over time.
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.
