How does the direction of acceleration affect the directions of motion?
The direction of acceleration affects the direction of motion by causing a change in velocity. If the acceleration is in the same direction as the velocity, the speed of the object increases. If the acceleration is opposite to the velocity, the speed decreases, and if the acceleration is perpendicular to the velocity, the object changes direction without changing speed.
When acceleration and velocity are in the same direction the speed will?
In that case, the speed will increase.
What happens to the speed when acceleration is in the same direction as the motion?
Speed increase constantly.
What moving object speed up in what direct is the acceleration?
The acceleration is the same direction of the velocity
Is the acceleration of an object always in the same direction of the net force?
No, the acceleration of an object is in the direction of the net force applied to it. If the net force is in the same direction as the object's motion, the acceleration will be in the same direction. If the net force is opposite to the object's motion, the acceleration will be in the opposite direction.
How is direction of acceleration related to direction of momentum?
It isn't. The direction of momentum is the same as the direction of the velocity - of the movement. The direction of acceleration, on the other hand, is the same as the direction of the net force that acts on an object - and this force can be in any direction.
What happens when velocity and acceleration are not in the same direction?
When velocity and acceleration are not in the same direction, the object's speed may be changing. If the acceleration and velocity are in opposite directions, the object will slow down. If they are at right angles to each other, the object will change direction without changing speed.
A car must always have an acceleration in the same direction as its velocity?
no
An object always accelerates in the same direction as what?
An acceleration is a change in velocity. Velocity is a vector quantity; it tells you about both an object's speed and its direction of travel (vectors are often represented as arrows; the length of the arrow is the magnitude, here the speed, and it points in the relevant direction). So you can see that a change in either an object's speed or direction counts as a change in velocity, and is therefore an acceleration.
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
Is acceleration always in the same direction as the unbalanced force?
No, acceleration is change in velocity. (And velocity is speed in a certain direction.) If an object slows down, then it is changing velocity and thus accelerating. (In this case, the acceleration is negative.) If an object changes direction, then it's velocity changes, so this is also acceleration. (This is centripetal acceleration.)
What happens to your speed when the acceleration is in the same direction as the motion?
When acceleration is in the same direction as motion, your speed will increase because the two are working together to propel you forward. This results in a faster rate of change in velocity, causing you to speed up.
