Why will a spinning top not stay in motion forever?
It tends to lose rotational energy due to friction.
What are day to day examples of rotational motion?
the spinning of earth around its axis, the motion of fan are some examples of rotational motion.
Can you give some types of kinetic energy?
There are many different forms of kinetic energy, but there are three that are most common. Linear Kinetic Energy (straight line motion) Rotational Kinetic Energy (Like a spinning top) Spring Kinetic Energy (A spring oscillating back and forth)
What type of energy is torque?
rotational energy
How does a windmill create energy?
Wind acting on the blades of a windmill causes it to spin around it's axis. This spinning motion is the conversion of mechanical, wind, energy to torque, mechanical rotational force. This drives a shaft for a pump or a generator.
Why does a scater go faster when she pulles her arm into her body?
A spinning skater posses a certain amount of rotational kinetic energy. kinetic energy is generally considered the energy of motion. For a spinning object (the skater) the energy is given by the equation KE = 1/2 time the rotational moment of inertia, times the square of the rotational speed. The rotational moment of inertia is given as I = the mass of the object times the square of the object's radius. When the skater is spinning with arms outstretched, the "radius is some value, r out. As the skater pulls arms in, the "radius decreases. However, the rotational energy remains constant, so the rotational speed has to go up. Mathematically, the equations are KE = 1/2 Ir x w squared, where w is the rotational speed. Because the kinetic energy is constant, the equations become 1/2 mrout squared x wout squared =1/2 m r in squared x w in squared. the factor 1/2 and the mass m cancel, so the governing equation becomes r out squared x w out squared = r in squared x w in squared, or, simplifying, r out w out = r in w in. Solving for w in, w in = (r out w out)/r in. As r in decreases, w in increases.
What is rotational energy?
energy that is energy in movement and the way the energy moved.
How does heat energy convert to rotational energy?
steam
What energy causes blades to spin?
Rotational energy
A basketball rolling across a flat floor has energy?
A basketball rolling across a flat floor has translational and rotational kinetic energy. There's a force of gravity pulling the ball down towards the floor, and a reaction force pushing the ball up away from the floor.
What does a wind turbine turn kinetic energy into?
Rotational energy, and then electrical energy.
What type of energy does a spinning have?
Mechanical Energy
