How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
When an object accelerates how does air resistance respond?
As an object accelerates, air resistance also increases due to the object moving through the air at a higher speed. This increased air resistance creates a force opposite to the direction of motion, ultimately slowing down the acceleration of the object.
What is an example of a motion in which acceleration is in direction of motion?
Throwing an object straight up in the air is an example of a motion in which acceleration is in the direction of motion. After the object is released, the acceleration due to gravity acts downward, which is in the same direction as the motion of the object as it goes up and then comes back down.
How are mass acceleration and air resistance related?
Mass acceleration and air resistance are related by Newton's second law of motion. As an object accelerates, air resistance acts in the opposite direction, slowing down the object. The greater the air resistance, the more it counteracts the acceleration of the object.
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.
What is the direction of the acceleration of an object that is slowing down while heading northward?
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
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.
When an object is speeding up to the right what direction is the acceleration?
The acceleration would be in the direction of the object's motion, which is to the right.
Is the acceleration the same on an object that is drop or when its thrown?
No, the acceleration is not the same for an object that is dropped and an object that is thrown. When an object is dropped, it experiences a constant acceleration due to gravity. When an object is thrown, its acceleration can vary depending on factors such as the initial velocity and direction.
If a moving object speeds upin what direction is the acceleration?
If a moving object is speeding up, the acceleration is in the same direction as the object's motion.
How can acceleration affect velocity?
Acceleration is the rate at which velocity changes. If an object experiences acceleration in the same direction as its velocity, its speed will increase. If acceleration is in the opposite direction of velocity, the object will slow down. Changes in acceleration can also affect the direction of velocity, causing the object to change direction.
Which force pushes against a moving object as it passes through air?
Air resistance, also known as drag, opposes the motion of an object as it moves through the air. This force increases as the speed of the object increases and can affect the object's velocity and acceleration.
How an object changes direction when a force is applied to it is called what?
The change in direction of an object when a force is applied to it is called "acceleration." The acceleration of an object depends on the magnitude and direction of the force, as well as the mass of the object.
Can the velocity of object reverse direction when its acceleration is constant?
Yes, the velocity of an object can reverse direction even when its acceleration is constant. This can happen when the object is subjected to an acceleration in the opposite direction to its initial velocity, causing it to slow down and eventually reverse direction.
