Can a body have constant velocity but still a varying acceleration explain?
No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion.
What is acceleration always in the direction of?
Keep in mind that although acceleration is in the direction of the change in velocity, it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion.
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.
Can a body have zero velocity and still be accelerated?
Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction.
Is it possible to have a northward velocity with Westward acceleration?
A westward acceleration while moving northward? Yes, an object can be moving at the same time that it is also slowing down. During this period, its acceleration is in the opposite direction of its 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.
