How is acceleration dependent on the speed and direction of an object?

Yes,it depends.Its reason is that we know from Newton's Second Law (F=m*a)**.
So force needed to accelerate the object is directly proportional to its mass.
**symbols have usual meanings.

∙ 14y agoAcceleration is just the change of velocity per unit time, so it doesn't matter at all what the velocity is.
However, if you are talking about the amount of force you need to apply to something in order to get a certain acceleration, F=ma, and m does change with velocity (only when you take relativity into account), so the faster you go, the more force you need to apply to get the same acceleration. This effect is extremely small for velocities which aren't close to the speed of light, though.

A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
What kind of motion does the speed and direction not change?
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
What is the rate at which speed or direction changes?
Acceleration
A force can cause an object to change its speed and or direction?
A force can cause an object to change its speed or direction. A force causes acceleration, as given by Newton's equation F=ma, where f is force, m is mass, and a is acceleration. Acceleration occurs when something either changes direction, like a tether ball is accelerating when it goes around the pole, or when the objects speeds up or slows down.Forces give energy to the object it is acting on.The more mass an object has, the harder it is to move, stop, or change the speed or direction of the object.An object will not start moving unless a force acts on it.An object will not stop moving unless a force acts on it.An object will not change speed unless a force acts on it.An object will not change direction unless a force acts on it.unbalanced
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
Velocity is the change of speed and/or direction of an object?
FALSE. Acceleration is the change of speed and/or direction of an object.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
No. For you to know acceleration you need the rate of change of speed and the direction.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
Acceleration is the change of speed and or direction of an object?
True
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
What is the defintion of acceleration?
Acceleration is any change in the speed and/or the direction of an object's motion.
Can an object with constant speed be accelerating?
Yes. 'Acceleration' means either speed or direction is changing. If direction is changing,then there is acceleration, even if speed is constant.
How does the direction of acceleration affect the directions of motion?
The acceleration will either speed up or slow down an object's motion in the direction it is applied. Any change in speed or direction is considered acceleration.
Is it possible for an object to have a negative acceleration and increasing speed at the same time?
No.The first part of your statement incorrect because it is impossible to have "negative acceleration". Accelertation is change in velocity over time. Velocity is speed and direction of a moving object. acceleration is not dependent on your direction. When is the last time your car was going -65 miles per second?
