What else can I help you with?
Is the acceleration of an object proportional to its weight?
No, acceleration is not directly proportional to weight. Weight is the force of gravity acting on an object, while acceleration depends on the net force acting on the object, which can be influenced by factors other than weight, such as friction or applied forces.
When forces are balanced compare the acceleration of an object at rest and an object in motion?
When forces are balanced, the object at rest will remain at rest, while the object in motion will continue to move at a constant velocity. This is due to Newton's first law of motion, which states that an object will remain at rest or in motion with constant velocity unless acted on by an unbalanced external force.
If a moving body has no acceleration does it mean that no force is acting on it?
It means there is no net force acting on it. A plane in the air has no acceleration, but it does have forces acting on it. Lift pushes it up Gravity pushes it down Air resistance opposes its movement Thrust provides movement When all these forces are equal the plane will move at a constant velocity. If one of these forces becomes greater the NET force on the plane will no longer be 0 and there will be an acceleration or deceleration. Hope that helps. Another example would be space as there are no opposing forces, if in space once a speed was that speed would be constant until you 1.) decelerated with a force in the opposite direction 2.) accelerated the speed past your current velocity in your current direction 3.) Get caught by some planets gravity and crash to you death (but then this question is the least of your problems)
What is the difference between vertical acceleration and horizontal acceleration?
Vertical acceleration is the rate of change of velocity moving up or down, while horizontal acceleration is the rate of change of velocity moving left or right. Vertical acceleration is affected by gravity, while horizontal acceleration is typically due to external forces like friction or thrust.
Why is an object in equilibrium during constant motion?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
What are the different forces acting on the ball while it’s in the air?
Gravity, force, and acceleration.
Are inertial and gravitational acceleration equal?
No, inertial and gravitational acceleration are not equal. Inertial acceleration is caused by changes in velocity due to forces acting on an object, while gravitational acceleration is caused by the force of gravity on an object due to its mass.
What are the forces acting on an object without acceleration?
The net force that is acting on an object that is not changing speed is centripetal force that is pulling the object into a circular path. However, just to be clear on this point, while the object's "speed" is not changing, it's "velocity" certainly is, because velocity, unlike speed, has a directional component to it.
Does a ball have acceleration while it is moving through the air?
Yes, a ball can have acceleration while moving through the air if its velocity is changing. This change in velocity can be due to forces like gravity or air resistance acting on the ball.
What is the difference between an object that has no force acting on it and an object that has a zero net force acting on it?
An object with no force acting on it means that there are no forces present at all, while an object with a zero net force means that the forces acting on it are balanced, resulting in no acceleration. In the second case, there may be individual forces present but their combination results in a net force of zero.
Is it true that the acceleration of an object is constant?
No, the acceleration of an object is not always constant. An object can have a variable or changing acceleration depending on the forces acting upon it. For example, an object in free fall has a constant acceleration due to gravity, while an object experiencing friction will have a changing acceleration.
Which forces cause a decrease in acceleration?
Friction and air resistance are two common forces that can cause a decrease in acceleration. Friction between surfaces can oppose motion, while air resistance acts against objects moving through the air, both reducing the net force acting on an object and therefore its acceleration.
Is the acceleration of an object proportional to its weight?
No, acceleration is not directly proportional to weight. Weight is the force of gravity acting on an object, while acceleration depends on the net force acting on the object, which can be influenced by factors other than weight, such as friction or applied forces.
How do net forces affect the acceleration of an object?
The acceleration of an object is directly proportional to the net force acting on it according to Newton's second law of motion. A larger net force results in a greater acceleration, while a smaller net force results in a slower acceleration. If the net force is zero, the object will either remain at rest or move at a constant velocity.
When forces are balanced compare the acceleration of an object at rest and an object in motion?
When forces are balanced, the object at rest will remain at rest, while the object in motion will continue to move at a constant velocity. This is due to Newton's first law of motion, which states that an object will remain at rest or in motion with constant velocity unless acted on by an unbalanced external force.
What are the forces acting on a shuttlecock when it falls vertically downward through the air?
The main forces acting on a shuttlecock falling vertically downward through the air are gravity pulling it down and air resistance pushing against its motion. Gravity accelerates the shuttlecock downward while air resistance slows its descent by pushing against its surface. These forces will determine the shuttlecock's acceleration and terminal velocity as it falls.
What happens to an object's acceleration as the size of the force acting on the object increases?
F=m.a , a=F/m; acceleration is directly proportional with force. acceleration increase while force increase.
