When does a mass accelerate uniformly?
A mass accelerates uniformly when a constant force is applied to it, resulting in a constant rate of change in velocity over time. This occurs in scenarios where there is no opposing force or acceleration due to factors such as friction, air resistance, or gravity.
In symbols when the applied force force applied -(blank) then Net (blank) and the object will travel with a constant (blank)?
In symbols, when the applied force ( F_{\text{applied}} ) is equal to the frictional force ( F_{\text{friction}} ), then the net force ( F_{\text{net}} ) is zero, and the object will travel with a constant velocity. This means that there is no acceleration, and the object maintains its state of motion.
Why LED is used to determine planks constant?
LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.
If the mass of an object does not change a constant net force on the object produces a constant what?
If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.
If a box is sliding along at a constant speed and the force of friction on the box is 100n what is the net force on the box?
If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
Use Newtons second law to determine how much force is being applied to an object that is traveling at a constant velocity?
If there is no force against motion,applied force is zero. If there is force against motion,applied force is equal and opposite to that force.
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
When an object is moving at a constant velocity, it means that the forces acting on it are balanced. In this case, the force of kinetic friction is equal and opposite to the applied force, making it easier to calculate the coefficient of kinetic friction using the known values of force and normal force.
If a car is traveling westward with a constant velocity of 20meters per seconds what is the net external force acting on it?
If the car is moving at a constant velocity, the net external force acting on it is zero. This is because the forces acting on the car (such as friction and air resistance) are balanced by the force applied by the engine to maintain the constant speed and direction.
How does mass affect velocity?
When mass increases, velocity remains constant if the force applied remains constant. However, if the applied force stays the same, an increase in mass will require more force to achieve the same acceleration, which may lead to a decrease in velocity.
What decreases on a constant impulse?
Velocity decreases on a constant impulse, as impulse is equal to the change in momentum. When a force is applied for a certain amount of time, it results in a change in momentum which causes the velocity to decrease at a constant rate.
Why you never see objects moving with constant velocity unless a net force is applied?
friction
Is velocity proportional to force with respect to newton's laws of motion?
No, not at all. As long as a constant force is applied, the velocity can continue to grow or shrink.
A bicycle is moving with constant velocity to the east. What is true of the applied forces?
The applied forces on the bicycle would be balanced. The force applied by the rider in pedaling is equal and opposite to the forces of friction and air resistance acting on the bicycle. This results in a net force of zero, allowing the bicycle to move with constant velocity.
When constant force is applied to a body then it does it moves with uniform speed?
When a constant force is applied to a body in the absence of other forces, it will accelerate according to Newton's Second Law (F=ma). If the force is balanced by friction or other opposing forces, the body will move with a constant velocity, resulting in uniform speed.
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
If the applied force were equal to the sliding friction force, the book would move at a constant velocity since the two forces would be balanced. This means there would be no acceleration or deceleration, and the book's velocity would remain unchanged as long as the forces stayed in equilibrium.
How are motion and acceleration different?
In Simple motion, there is no force being applied. The moving object moves in a straight line with constant velocity. In acceleration, there is a force applied. The object's velocity is changing. The first derivative of acceleration is velocity. The first derivative of velocity is distance. (Derivative is a calculus thing.)
