What else can I help you with?
Can resistance speed up moving objects as well as slowing them down?
Resistance can slow down moving objects by opposing their motion, but it cannot speed them up. When an object encounters resistance, such as air resistance or friction, it must overcome these forces to maintain its speed or acceleration. The resistance acts as a hindrance that requires additional force or energy to counteract.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
What must be true about an object that serves as a reference point?
An object serving as a reference point must be stationary or moving at a constant velocity to accurately measure the motion of other objects relative to it. It should also have a known position in space to allow for precise comparisons and calculations.
What must be absent for two objects of drastically different masses to fall at the exact same speed if they rely only on gravity?
Air resistance must be absent for two objects of drastically different masses to fall at the exact same speed when relying only on gravity. This is because air resistance affects the rate at which objects fall through the atmosphere, causing lighter objects to experience more air resistance than heavier objects.
What must be applied to a objects in order change the objects motion or direction?
A force must be applied to an object in order to change its motion or direction. This force can be in the form of a push or pull exerted on the object. The magnitude and direction of the force applied will determine how the object's motion changes.
What do you mean by drag forceexplain why objects moving in fluids must have special shape?
Drag force is a resistance force exerted by a fluid (like air or water) on an object moving through it. Objects moving in fluids must have a special shape to minimize drag force and enhance their motion efficiency. The shape is designed to reduce turbulence and separation of flow, which helps the object move through the fluid with less resistance.
What is the Definition of resistance force?
Resistance force is a force that acts in the opposite direction to the motion of an object, making it difficult for the object to move. It is typically caused by factors such as friction, air resistance, or contact with another surface. This force opposes the motion or change in motion of the object.
Why remove resister from circuit to measure resistance?
a meter uses its own supply to measure resistance. you dont have to remove the resistor from the circuit but you must isolate it from the circuit supply to get an accurate reading.
Is mass related to inertia?
Inertia states that an object in motion will stay in motion unless another force acts against this object. The larger the mass the object has, the more force must be used to go against its movement. In this way, mass relates to inertia.
Why is there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
What is resistance to motion?
Resistance to motion is the force that opposes the movement of an object through a medium, such as air or water. This force can be caused by factors like friction and drag, which slow down the object's motion. Ultimately, resistance to motion can make it more difficult for an object to move quickly or efficiently.
What factors are necessary for an object to be in motion?
Inertia is required for an object to be in motion, which is the tendency of an object to resist changes in its state of motion. Additionally, an external force must be applied to overcome any friction or resistance that may impede the object's motion.
