What is the acceleration towards the inside of a curved path?
"Acceleration" does not mean "speeding up". Acceleration means any changein the speed or direction of motion. An object with no acceleration moves at aconstant speed in a straight line. If its path is not straight, then the directionof its motion changes, which fits the definition of acceleration.
What is the example where acceleration is in the direction of motion?
An example of acceleration in the direction of motion is a smooth spherical stone dropped from the roof of a building on a windless day. All the motion is straight down, toward the center of the earth, and so is the acceleration.
What is the acceleration at highest pointn when ball is thrown straight up?
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
When A ball is thrown straight up from the ground. What way does its acceleration point at the top?
Its acceleration points straight down at all times after it's released.
What is the acceleration of a car moving along a straight line path that increases its speed from zero?
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
Does a particle moving in a straight line have acceleration?
A particle moving in a straight line may or may not have acceleration. Acceleration is adifferent phenomenon altogether. the rate of change of velocity is acceleration, a particle can move in a straight line with a constant velocity thus having no acceleration & it can also move with increasing or decreasing velocities thereby accelerating or deaccelerating.

When can you accelerate even when your speed doesn't change?
"Acceleration" means a change of speed or direction of motion, or both.If you change direction ... like turning a corner ... then there is acceleration,even though your speed is constant.Anything traveling on a circular track, even at a constant speed, has constantacceleration.
When a car rounds a curve it's acceleration is zero?
Actually, a car always accelerates on a curve. This is because acceleration, like the velocity it alters, is a vector that has both magnitude and direction. Since taking a curve involves a change of direction, there must be an acceleration to alter the direction; otherwise, the car can only continue straight.
What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
Can a velocity be reversed if acceleration is constant?
Sure. A pendulum, a child's playground swing, and a bullet shot straight up all have constant acceleration, and all reverse direction.
Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
