Conditions in which the body is accelerating?
According to Newton's laws, the conditions in which a body accelerates are only those in which a force is acting upon it. With no force acting upon it, a body would not accelerate. With a force acting upon it, it would accelerate by an amount proportional to the force and inversely proportional to its mass.
Is rolling friction greater than sliding friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
What force is required to move an object when there is no friction?
That depends. If the object is free falling then Fg (force of gravity[9.81m/s^2 near earths surface]) would be a force acting upon the object as well as air resistance working in the other direction. If the object is on a frictionless surface, then Fn (normal force) Fg(gravitational force), and Fa(force applied to the object) would be the forces acting upon it. The equation for calculating net force is Fnet=ma m=mass in kg a=acceleration(m/s^2) Hope this helps!
What is an object called when the only force acting upon it is gravity?
Let me think.......Why should I tell?
What happens when Rubbing iron with sand paper?
What happens when you rub sandpaper back and forth over a piece of wood? The strength of the friction force depends upon the types of surfaces involved and how hard the surfaces push together.
What force is not acting upon a ball that is thrown in the air?
The force of friction is not acting upon a ball that is thrown in the air. Friction is a force that opposes motion, but when a ball is thrown in the air, there is no surface contact for friction to act upon.
When you are running on a road you are acted upon by frictional force of the road.Is there another force of friction acting on you?
Yes, the force of static friction is also acting between the soles of your shoes and the road surface to help propel you forward while running. This force allows you to push off the ground and move in the direction you want.
When there is no friction a gliding puck will what?
When there is no friction, a gliding puck will continue moving in a straight line at a constant velocity indefinitely because there are no external forces acting upon it to slow it down or change its direction.
How much friction is produced by brakes to stop a vehicle running at 80kmhr?
friction acting btw the road surface and wheel depends upon the braking retardation of the vehicle. every surface has its own friction coefficient which represents the maximum value , however friction can act in range from 0 to that max value , and this value depends upon the braking retardation.
I want 8 class book download online?
There are two main types of friction: kinetic and static. Static friction resist impending motion: the force needed to break before something starts sliding. Static friction stops acting upon the object once it starts moving. Kinetic friction resist motion: the force that is opposing existing motion, i.e. object has already started sliding.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
Why do objects slide?
Objects slide because of the forces acting upon them, such as gravity or friction. When an object is on a sloped surface, gravity pulls it downward, causing it to move. The presence of friction between the object and the surface affects how easily the object slides.
Infer whether balanced forces must be acting on a car moving at a constant speed?
Yes, if a car is moving at a constant speed, balanced forces must be acting on it. This means that the force pushing the car forward is equal to the resistive forces acting against it (like friction and air resistance), resulting in zero net force and a constant velocity.
What type of friction has the most friction?
Static friction typically has more friction than kinetic friction. Static friction occurs when an object is not moving, and the friction force is at its maximum to prevent the object from moving. Once the object overcomes static friction and starts moving, the friction force decreases to kinetic friction.
Is sliding friction greater than rolling friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
What would happen to the ball if there were no friction or obstacles to run into?
If there were no friction or obstacles, the ball would roll in a straight line indefinitely due to inertia. Without any forces acting upon it, the ball would maintain its velocity and direction.
How does a balloon hovercraft work does it have lots of forces acting on it and what does friction have to do with it?
A balloon hovercraft works by releasing air from the balloon to create a cushion of air that reduces friction with the surface. The lack of friction allows the hovercraft to move smoothly over the surface. The main forces acting on the hovercraft are thrust, lift, and gravity, which work together to keep it hovering.
