What is the direction of acceleration in circular motion?
An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. The animation at the right depicts this by means of a vector arrow.
Can the velocity of an object be in a direction other than the direction of acceleration?
Can the velocity of an object be in a direction other than the direction of acceleration of the object? Yes, Velocity of a body and its acceleration may be in different directions. Explanation: 1) Incase of vertically projected body⇒ velocity of body is in the upward direction and acceleration is in downward direction.
Can the velocity of an object be in a direction other than the direction of acceleration of object write with examples?
yes ,in case of retardation,the direction of velocity and the acceleration are opposite to each other. this is possible because both velocity and the acceleration are vector quantities. in case when the velocity decreases,here actually means that the direction of acceleration is opposite to that of velocity.
Can you have motion in two direction and acceleration in one direction?
Yes, there can be motion in two dimension with an acceleration only in one dimension. Example: Consider a ball thrown at an angle with the horizontal. The acceleration in the vertically downward direction is ‘g’. So, we have a 2 dimensional motion with an acceleration only in 1 dimension.
Is it possible to have acceleration when velocity is zero?
If the velocity is constant however, the acceleration is zero (because the velocity isn’t changing over time). Although at an instant in time it is possible to have zero velocity whilst accelerating. For example, if you drop an object at the instant you release it it has zero velocity but it is accelerating.
What is a westward acceleration?
Accelerating objects have a changing velocity – either due to a speed change (speeding up or slowing down) or a direction change. A car moving eastward would be described as having an eastward velocity. And a car moving westward would be described as having a westward velocity.
Can a car traveling west simultaneously have an acceleration pointing east?
Yes. When it is slowing down it has negative acceleration (also called “deceleration”) with respect to the eastward direction. Negative acceleration with regard to the eastward direction is the exact same thing as positive acceleration in the westward direction.
Can the equations above be used in a situation where the acceleration varies with time?
Can the equations of kinematics be used in a situation in which acceleration varies with time? No, they can only be used when acceleration is constant.
Can an object accelerate even if its speed is constant quizlet?
Yes. Velocity and acceleration need not be in the same direction. Any object moving in a circle or along a curve is changing velocity (accelerating) even if its speed is constant, because its direction is changing.
Is it possible to move in a curved path in the absence of a force Defend your answer?
Is it possible to move in a curved path in the absence of a force? No. With no forces, path would be straight line.
Is it possible for a particle to describe a curved path if no force acts on it?
No, it is NOT possible to go under a curved path without the action of a force. If the particle needs to go under a curved path, it will always need a centripetal force.
Does an object’s inertia depend on its mass?
The inertia of an object is a measure of its resistance to a change in the state of its motion. It is solely dependent on the mass of the object, with more massive objects having larger inertia and a greater tendency to resist changes to their motion.
On which factor does the inertia of rest depend?
Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object. More the mass of an object, more is the inertia of the body.
Which has more inertia cricket ball or rubber ball?
Inertia of abody depends on its mass. a cricket ball has more mass than a rubber ball, hence it has more inertia.
