- Rubbing a balloon against your hair.
- Sliding a book across a table.
- Skating on ice.
- Walking on a rough surface.
Options 1, 2, and 4 are examples of friction as they involve surfaces rubbing against each other, creating resistance. Skating on ice, however, involves very little friction due to the minimal contact between the skate blade and the ice surface.

When an object moves in a circle what acts to accelerate the object torward the center of that circle?
The centripetal force acts to accelerate the object toward the center of the circle. This force is directed inward and is required to keep the object moving in a circular path. It is provided by tension, gravity, friction, or any force that is directed towards the center of rotation.
Projectile following a parabolic path on a circle?
A projectile following a parabolic path on a circle can be understood as the motion of an object launched at an angle along the circumference of the circle. As the object moves, gravity causes it to follow a parabolic trajectory while the curvature of the circle influences its path. The resulting motion combines the circular motion of the circle with the parabolic motion of the projectile.
What are two sources of friction?
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.
What does a radius in a circle looks like show picture?
I'm unable to show pictures. But a radius in a circle is a line segment that connects the center of the circle to any point on the circle's circumference. It is half the length of the diameter of the circle.
What is friction what are four types of friction?
Friction is most commonly known as any push or pull. There are four types of friction ; sliding friction, static friction, rolling friction, and fluid friction. Sliding friction is when something is sliding against another surface. Static friction is when there is force being applied upon a heavy object or the object is being moved on a rough surface. Rolling friction is when something is rolling on a surface and friction slows it down. Finally, fluid friction is when an object is being slown down on or in water, air, or any others fluid.
Which are the examples and non examples of radius in math?
Some examples and non example of a radius in math are: Examples - the distance from the center of a ball to the outer edge. The difference from the center of a circle to the outer edge. Non example - the length of a square, the entire length across a circle or ball, the distance around the perimeter of a circle.
What are non examples of radius in math?
Non-examples of radius in math include concepts such as diameter, which measures the distance across a circle through its center, and circumference, the total distance around the circle. Additionally, a line segment that does not connect the center to the edge of the circle, such as a chord that does not pass through the center, is not a radius. Other non-examples include any measurements related to polygons or other shapes that do not involve a circle.
What shape has the same perimeter but not the same area?
Begs the question: Same perimeter as what? There are plenty of examples of shapes that given the same perimeter length will have different areas, e.g. pick any two of the following: Circle, Square, Triangle, Rhombus, Pentagon, Hexagon...
Definition of friction rolling friction sliding friction and fluid friction make it simple.?
Rolling Friction is caused by a rolling object such as a wheel when rolling over a surface. Sliding friction is cause by the brishing of an object along with the medium that it is sliding on. This can be visualize by sliding down a hill with a sled in the snow. Fluid friction, by fluid we are alluding to any substance that flows. Therefore air and water for both examples are fluid. When swimming or when is a bird is flying fluid friction is being acted upon them Good luck Stephane E. Fouche
Is there any friction besides fluid friction in swimming?
There is 'skin friction' also know as drag. There is also lubricated friction.

Is a circle a quadralateral?
A quadrilateral is a polygon ("many angled") with 4 sides that intersect. Since a circle doesn't have any sides, it cannot be a polygon. A square, a trapezoid, a parallellogram, a rhombus, or a rectangle would all be examples of shapes that ARE polygons.
What is the segment from the center of a circle to any point on the circle?
It is the circle's radius
The distance from the centre of the circle to any point on the circle?
It is the radius of the circle
What are some real life examples of a arc shape?
A rainbow is an example of an arc shape, as is any object or drawing that has a curve conforming to a section of the the circumference of a circle.
What connects a circle to the center of the circle?
A RADIUS connects the center of a circle to any point on the circle.
