Will a heavy bobsled go down a track faster than a light one?
A little. Momentum is mass times velocity. The more momentum and object has the harder it is to stop. So the more momentum a bobsled has the more effective it will be against the forces trying to slow it down such as friction, wind resistance, drag, etc. However, this does assume that the bobsled team can get the heavier sled up to the same speed as a lighter one.
Why ping pong ball rolls in air for longer time?
A ping pong ball rolls for a longer time in air due to its low mass and high surface area, which results in less air resistance compared to heavier or more aerodynamic objects. This lower air resistance allows the ball to maintain its speed and momentum for a longer period before coming to a stop.
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.
Is nitrogen heavier than oxygen?
it is heavier
In a gel electrophoresis's why are the lines closer together when the DNA strands are heavier?
Heavier DNA strands move slower through the gel due to their larger size and mass, causing them to travel shorter distances during the same amount of time compared to lighter DNA strands. This results in the heavier DNA bands being closer together on the gel, as they have not traveled as far as the lighter bands in the same time frame.
How do different weights affect friction?
Friction is a resistance force imparted on an object sliding across a surface where the force is directly proportional to the WEIGHT of the object. The heavier the object that is moving across the surface the higher the frictional forces.
What is the resistance or drag you encounter when you pull an object across the floor?
The resistance or drag you encounter when pulling an object across the floor is mainly due to friction between the object and the floor surface. This frictional force opposes the motion of the object and makes it harder to move. The rougher the surface or the heavier the object, the greater the resistance or drag will be.
What two things influence the size of a friction force?
The size of a friction force is influenced by the weight of the object and the roughness of the surfaces in contact. A heavier object will exert a greater frictional force, while rougher surfaces create more resistance and increase friction.
Why does a heavier person slide down a hill faster than a lighter person when on a snow tube?
because the heavier person has more initeria and therefore the forces that would slow the slider down i.e friction, wind resistance, whatever, have less effect on a heavier person that a lighter person
Does weight affects friction?
Yes, weight does affect friction. With an increase in weight, there is usually an increase in the force pressing objects together, resulting in higher friction between the surfaces. This means that heavier objects may experience greater friction compared to lighter objects.
Why does a heavier person go down the slide faster?
because a heavier person has more inertia, and therefore the forces that work to slow the person down, i.e. friction, wind resistance, whatever, will have less effect on an object with more inertia than less inertia
How does the mass of sliding object affect friction?
The mass of a sliding object does not directly affect friction. Friction is primarily influenced by the nature of the surfaces in contact and the normal force pressing them together. However, in some cases, a heavier object may increase the normal force, which in turn can increase the friction force.
What causes more friction?
Rough surfaces or heavier objects typically cause more friction because there is more contact area between the surfaces, creating greater resistance to motion. Additionally, increased pressure between the surfaces can also lead to more friction.
What are two factors that can affect speed?
Thrust and friction in the environment. Ignoring friction, the two chief factors are the force of acceleration and mass, which determines how much force is required to achieve a given speed (more technically the change of velocity: speed in a given direction).
How does friction stop something from moving?
There are normally four forces acting on a body. They are friction force, applied force, weight and gravity. Friction is an opposing force that creates resistance to a body causing it to slow down. e.g If we have a car accelerating 1.55ms-2 and it weighs about 1400kg with its passenger and fuel. The applied force would be 2100N. The air resistance or drag force and the friction of the tries between the surface of the road has generated about 19500N. If we take away the friction force from the applied force, 2100N - 19500N = 600N of applied force to keep the car going but remember that this friction force will gradually slow down the car.
What are advantages of wheel?
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
When friction is greater when surface have more is it gravity or roughness?
Both. Suppose you want to move something over the ground. If it becomes heavier then it will be subject to more friction on account of gravity. If it's lower surface becomes rougher then again, it will be subject to more friction. The force pressing two surfaces together and the roughness of the two surfaces act together to produce friction.
