Rolling friction .<span> the force that slows down the movement of a rolling object</span>
sliding friction.
Sliding friction : The opposing force that comes into play when one body is actually sliding over the surface of the other body is called sliding friction. e.g. A flat block is moving over a horizontal table.

Kinetic or dynamic friction: If the applied force is increased further and sets the body in motion, the friction opposing the motion is called kinetic friction

The three types of friction are the Static friction, Kinetic friction and the Rolling friction.

Further Explanation:

The friction between the two surfaces is the resistive force that acts between the surfaces such that it opposes the relative motion between the surfaces.

The Static friction is the friction force that is required to make an object move from rest. The static friction force is the maximum friction force experienced by a body whereas the body is considered to be under the kinetic friction when it starts to move. The friction force acting on a body while it is sliding over a surface is termed as the kinetic friction of the body.

The rolling friction is a friction force experienced by the circular or a spherical body as it rolls on a surface. In rolling friction, there is no sliding between the surfaces.

Thus, the three types of friction act on a body depending on the shape of the body and also depending on the state of rest or motion of the body.

A square wire, 20 cm on the side, moves at constant speed parallel to the xy-plane into a region where there is a uniform magnet
Amanda [17]

Answer:

The speed of the wire is 5 m/s.

Explanation:

Given that,

Length = 20 cm

Magnetic field = 0.1 T

Current = 10 mA

Resistance R= 10\Omega

We need to calculate the  speed of the wire

Using formula of emf

\epsilon=Bvl

Using formula of current

I=\dfrac{\epsilon}{R}

Put the value of \epsilon into the formula of current

I=\dfrac{Bvl}{R}

v=\dfrac{IR}{Bl}

v=\dfrac{10\times10^{-3}\times10}{0.1\times20\times10^{-2}}

v= 5\ m/s

Hence, The speed of the wire is 5 m/s.

How high a hill can a car coast up (engine disengaged) if work done by friction is negligible and
aev [14]

Answer:

h= 46.66 m

Explanation:

Given that

Initial speed of the car ,u = 110 km/h

We know that

1 km/h= 0.277 m/s

u= 30.55 m/s

lets height gain by car is h.

The final speed of the car will be zero at height h.

v²=u²- 2 g h

v= 0 m/s

0²=30.55²- 2 x 10 x h           ( g = 10 m/s²)

h= 46.66 m
