How do you find the acceleration?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
What quantities changes at a constant rate in a body in uniformly accelerated motion?
Constant acceleration means velocity changing at a constant rate since the rate of change of velocity is acceleration (first equation of motion).
Does a body have acceleration in the following situations Why?
If either speed or direction changes, the velocity is non-uniform. Acceleration is the rate of change in velocity. Hence, a body travelling along a straight line with non-uniform velocity will have acceleration because it covers unequal displacements in equal intervals of time.
Can a body have zero velocity and still be acceleration?
A bode can have acceleration without zero velocity. For eg. when an object is thrown upwards, then at the maximum height, velocity at body is zero at that instant but it has acceleration due to gravity.
What is the example of an object with a constant acceleration but zero velocity?
One example of this is the vertical motion of an object. When the object is thrown upwards and reaches the maximum height, the velocity of the body becomes zero, but it still accelerates with constant acceleration. The constant acceleration is due to gravity.
In which of the following situation is the object accelerating?
An object is accelerating if it is changing its velocity.
Which of the following is not an example of acceleration?
The correct option is D An object moving with a constant velocity.
Which refers to an object moving with a constant acceleration?
Velocity vector is v (t)=∣v ∣v^ If acceleration is constant, velocity uniformly change with time.
Which situation shows an object is not accelerating?
Objects are NOT accelerating if they are traveling in a straight line at constant speed.
Can an object at rest have acceleration?
Yes, acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest. An example is a vertically thrown ball at the top of its trajectory, or a yo-yo just as it turns around.
Can a body be at rest and still accelerating?
Hello yaar, Yes, a body can have acceleration while at rest. For Example:- i)The best example for this is acceleration due to gravity(g). It acts on a body even if the body has no velocity.
