Physics - ICS Part 1 Physics Chapter 5 Short Questions Test

Question # 1

Define angular displacement and write its S.I unit.

Ans 1:

Question # 2

How is artificial gravity created?

Ans 1: Artificial gravity is the gravity like effect produced in an orbiting spaceship to overcome weightlessness.To create artificial gravity the spaceship is set into rotation around its own axis. The astronaut then is presses towards the outer rim and exerts a force on the floor of the spaceship in much the same way as on the earth.

Question # 3

Why banked tracks are needed for turns?

Ans 1: Banked tracks are needed because friction alone cannot provide energy for centripetal force.
If the road is banked, so that the outer edge is above the inner edge, then a portion of the normal force from the road on the tyre points towards the center of the track; this fraction of the normal force can provide enough centripetal force to keep the car moving in a circle.

Question # 4

What is meant by INTEL SAT? At what frequencies the INELSAT-VI operates ?

Ans 1: The largest satellite system managed by 126 countries is international. Telecommunication Satellite Organization (INTELSAT).
The INELSAT-VI operates at microwaves frequencies of 4, 6, 11 and 14 Ghz.

Question # 5

Explain why earth's satellite despite of being freely falling object does not reach the earth.

Ans 1: To orbit the planet and not come crashing down, a spacecraft has to travel forward (tangential to Earth ) fast enough that it compensates for the fall downwards. The trajectory of its fall has the same curvature as earth's surface. So it will never reach the earth.

Question # 6

What is meant by moment of inertia? Explain its significance.

Ans 1: The product of mass of the particle and square of its perpendicular distance from the axis of rotation is called the moment of inertia.

I =mr²
^{The moment of inertia plays the same role in angular motion as the mass in linear motion.}

Question # 7

Explain the difference between tangential velocity and angular velocity.

Ans 1: The linear velocity of a particle moving along a curve or circle is called tangential velocity. Its direction is always along the tangent to the circle.
The rate of change of angular displacement is called angular velocity.The direction of angular velocity is along the axis of rotation of the body by right hand rule. V= rw

Question # 8

What are Artificial Satellites?

Ans 1: Artificial Satellites are the man-made objects that orbit around the Earth.

Question # 9

What is mean by angular momentum?

Ans 1:

Question # 10

How would you determine the direction of angular momentum?

Ans 1: The direction of angular momentum can be determined by right hand rule:
"Grasp the axis of rotation in right hand with the figures curling in the direction rotation then the erect thumb will give the direction of angular momentum."

Question # 1

An object orbiting around the earth in said to be a freely falling body. Why?

Ans 1: An object in orbits is said to be freely falling , because the trajectory of its fall has the same curvature as Earth's surface. In fact, the object is falling towards the center of earth but because of spherical shape of earth, it never reaches the surface of earth.

Question # 2

What is meant by centripetal force? Write down its formula.

Ans 1:

Question # 3

What are geostationary orbit and geostationary satellites?

Ans 1: Geostationary Orbit: An orbit in which the time period of satellite is equal to the time period of spin motion of the earth is called geostationary orbit.

Geostationary Satellites: A satellite whose orbital motion is stationary along the earth is called geostationary satellite.

Question # 4

Define angular momentum and give its dimension.

Ans 1:

Question # 5

Why is the axis of rotation of Earth remains fixed in one direction with respect to the universe around it?

Ans 1: The major force acting on Earth is the pull of the Sun and no other sizeable toque is experienced by it. The Earth's axis of rotation, therefore remains fixed in one direction with reference to the universe around us.

Question # 6

How is artificial gravity created?

Ans 1: Artificial gravity is the gravity like effect produced in an orbiting spaceship to overcome weightlessness.To create artificial gravity the spaceship is set into rotation around its own axis. The astronaut then is presses towards the outer rim and exerts a force on the floor of the spaceship in much the same way as on the earth.

Question # 7

State the direction of the following vectors in simple situation:
A) Angular Momentum B) Angular Velocity

Ans 1: The direction of angular momentum and angular velocity can be determined by right hand rule;
"Grasp the axis of rotation in right hand with the figures curling in the direction of rotation, then the erect thumb will give the direction of angular velocity and angular momentum."

Question # 8

Define centripetal force and centripetal acceleration.

Ans 1: The force needed to bend the normally straight path of the particle into a circular path is called the centripetal force.
The instantaneous acceleration of an object traveling with uniform speed in a circle is directed towards the centre of the circle and is called centripetal acceleration.

Question # 9

Define centripetal force; write its formula and unit.
