## How do you test for centripetal force?

Measuring the variables involved in circular motion, to find out whether the formula for centripetal acceleration, F = mv 2R, is reasonable.

Why does the spring stretch in your experiment when the object moves in a circular path?

In this experiment, you will measure the force on an object of known mass which is attached by a spring to a rotating shaft on a very low friction bearing. You will rotate the shaft at a constant speed. Because of the object’s inertia, it will appear to fly out. As it flies out, it will stretch a spring.

What is an example of circular motion from everyday life?

The planets revolving around the sun is a prominent example of circular motion in real life. The planets tend to follow a fixed circular orbit that acts as the boundary of the circle, while the sun acts as the centre of the circular path.

### What is difference between centripetal and centrifugal force?

Centripetal force is the component of force acting on an object in curvilinear motion which is directed towards the axis of rotation or centre of curvature. Centrifugal force is a pseudo force in a circular motion which acts along the radius and is directed away from the centre of the circle.

What are three examples of circular?

Some of the most common examples of circular motion include man-made satellite that revolves around the earth, a rotating ceiling fan, a moving car’s wheel, the blades in a windmill, and gears in gas turbines. A particle is said to execute circular motion when it moves along the circumference of a circular path.

What can you say about objects moving in circular motion?

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.

#### What happens to a body when whirled in a circular path?

When a body is whirled in a circle the work done is zero because in circular motion displacement is always perpendicular to the applied force. Also when a body moves along a circular path then the centripetal force acts along the radius of the circle and is at right angle to the motion of the body .

Why does the spring stretch more when we increase the radius of the circular path?

The spring will stretch because it has inertia as it moves in the circle – constant force is required to keep its direction of motion turning – this force stretches the spring.

How does circular motion relate to real life?

## What sports use circular motion?

Circular motion is common to almost all sporting events. Whether it is sports car racing or track and field, baseball running or ice-skating, the motion of objects in circles is a common observation of sports viewers around the world.

What are some practical uses of circular forces cite three examples?

Examples

• Loop of Roller Coaster. Loops of a roller coaster are constructed in a teardrop shape that is commonly referred to as a clothoid.
• Orbiting Planets.
• Twirling a Lasso.
• Electrons Orbiting around Nucleus.
• Driving on Curves.
• Cream Separator.
• Washing Machine Dryer.

What are the applications of circular motion?

Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a mechanism.

### What are five examples of circular motion?

– Motion of wheel – The motion of child sitting on merry go round. – Whirling around of a hammer tied to chain before throwing it

What is the formula for circular motion?

α = dω/dt = d 2 θ/dt 2. Circular motion can be uniform and non-uniform depending on the nature of acceleration of the particle. The motion is called uniform circular motion when the particle is moving along a circular path possessing a constant speed.

What is circular motion and its examples?

Motion of artificial satellites around the earth is an example of uniform circular motion.

• The motion of electrons around its nucleus.
• The motion of blades of the windmills.
• The tip of second’s hand of a watch with circular dial shows uniform circular motion.
• #### How is circular motion different from rotatory motion?

The earth rotating about its axis.

• A top,like the one in Inception,spinning about its axis.
• A whirlpool,sucking in unlucky ships that cross its path.
• A tornado,destroying crop fields and ripping the roofs off houses.
• A windmill,rotating from the strong winds blowing.
• A bowling ball,rolling along to hit a strike (or a spare).
