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.
What is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Is acceleration how quickly an object's velocity changes?
Yes, acceleration is the how the velocity changes. This also includes when an object turns
An example of acceleration against the direction of motion?
If an object is moving to the right with a velocity vector of 5 m/s, and then a force is applied to the left causing the object to slow down, it experiences acceleration against the direction of motion. This acceleration would act in the left direction, opposing the object's initial motion to the right.
How do you find an objecets acceleration from its mass and force acting on it?
You can find an object's acceleration by dividing the force acting on it by its mass. The formula is: acceleration = force / mass. This will give you the acceleration of the object in the direction of the force.
If an object is speeding up to the right what direction does its velocity vector point?
The velocity vector of an object that is speeding up to the right points in the same direction, to the right. Velocity is a vector quantity that includes both magnitude (speed) and direction, so as the object accelerates, the velocity vector will align with the direction of motion.
What occurs any time an object speeds up or slows down or changes direction?
Acceleration. Acceleration is change in velocity. Velocity is its speed and direction. So when one of these things changes, it is undergoing acceleration. Acceleration can be the object speeding up, slowing down, turning right, turning left, etc. Deceleration is lowering the rate of change. You are experiencing no change if you are moving in a straight line at a constant speed.
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.
Is it possible for an object to have an acceleration when the speed of the object is constant?
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
What is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Is acceleration how quickly an object's velocity changes?
Yes, acceleration is the how the velocity changes. This also includes when an object turns

If an object is moving to the right with a velocity vector of 5 m/s, and then a force is applied to the left causing the object to slow down, it experiences acceleration against the direction of motion. This acceleration would act in the left direction, opposing the object's initial motion to the right.
An unbalanced force to the left accelerates an object in what direction?
The application of force on object (without opposing forces) results in acceleration in the direction of the vector. In this case the unbalanced force to the left will accelerate the object to the right.
How do you find an objecets acceleration from its mass and force acting on it?
You can find an object's acceleration by dividing the force acting on it by its mass. The formula is: acceleration = force / mass. This will give you the acceleration of the object in the direction of the force.
What is the difference between tangential and radial acceleration?
Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.
Explain the difference between positive and negative acceleration?
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
