What else can I help you with?
Is there any point along the path of projectile where velocity and acceleration vectors are perpendicular to each other?
Using the term "trajectory" implies that the acceleration you are concerned about is due to gravity. Gravity will always be perpendicular to the surface. Unless the trajectory begins perpendicular to the surface, it will never change to become perpendicular and the velocity will never be in a direction parallel to the acceleration. If it starts perpendicular to the surface it will start and remain perpendicular. Of course if you have another force acting on the object - such as wind - the component of the velocity vector parallel to the ground could be reduced to zero and at that point the only remaining component of the velocity vector would be that perpendicular to the ground and parallel to the acceleration. Likewise if the object is being propelled by an engine or rocket, the trajectory could be parallel to the force any time the acceleration vector became parallel to the velocity vector.
What is the relationship between radial and tangential acceleration in circular motion?
In circular motion, radial acceleration is perpendicular to the velocity and points towards the center of the circle, while tangential acceleration is parallel to the velocity and changes the speed of the object. The two accelerations are independent of each other and can act simultaneously in different directions.
Is it possible that the velocity of an object be in a direction other than the direction of accalaration?
Of course. When you toss a ball or a stone UP into the air, thenfor all the time until it reaches its peak and begins to fall, its velocityis upward but its acceleration is downward.The acceleration of gravity is always downward, but material objectsfrequently have upward velocities.In any situation where an object's acceleration is opposite to its velocity,a Physicist would say that the object is "slowing down".Another example is motion at a steady speed in a circle. In that case, theacceleration and velocity are always perpendicular. The acceleration actsonly to change the direction of the object's motion, but not its speed.
Can velocity and acceleration point in opposite direction?
Yes, velocity and acceleration can point in the opposite direction to each other. This is because neither one depends on the other. When velocity and acceleration are opposite each other this results in slowing down, for example when you hit the break on your car.
What happens when your velocity and net force are perpendicular to each other?
When velocity and net force are perpendicular to each other, the force does not affect the speed of the object, but instead changes the direction of the velocity. The object will move in a curved path due to the force causing it to accelerate in a direction perpendicular to its velocity. This is described by the principle of circular motion.
Let v and a represent the velocity and accelerationrespestivelyof an automobileDescribe circumstances in whichv and a are parallelv and a are antiparallelv and a are perpendicular to one another?
When they are parallel, the automobile has a positive acceleration (it is speeding up). When they are antiparallel (I assume you mean at 180 degrees to each other but in the opposite direction), the automobile has a negative acceleration (it is slowing down). When they are perpendicular they have no effect on each other, therefore the car has a constant velocity.
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.

The two accelerations are independent of each other and can act simultaneously in different directions.
How are acceleration and velocity alike and different from each other?
-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes

The object will move in a curved path due to the force causing it to accelerate in a direction perpendicular to its velocity. This is described by the principle of circular motion.
Do velocity and acceleration of an object have to be in the same direction?
Yes because velocity vector is got by the product of acceleration vector and time which is scalar. v = a t (Except when you toss a ball upward, and until it reaches the top, it has upward velocity and downward acceleration. But in all other situations except for that one.) (And except when a yo-yo or an artificial satellite is moving in a circle, and its velocity is always tangent to the circle but its acceleration is always toward the center of the circle. But definitely in all other situations except for that one.)
Is there any point along the path of projectile where velocity and acceleration vectors are parallel to each other?
Yes, at the highest point of the projectile's trajectory, the velocity and acceleration vectors are parallel to each other. This is because the velocity is momentarily zero, and the acceleration due to gravity is acting vertically downward, pointing in the same direction as the velocity.
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.
When is velocity antiparallel to acceleration?
Velocity is antiparallel to acceleration when an object is moving in the opposite direction of the acceleration. This means that the object is slowing down due to the acceleration acting in the opposite direction to the object's motion.
