Motion of a Ball on an Inclined Track
 1) Identify the force responsible for acceleration of a ball down the inclined plane? Cosine component of gravitational force Frictional force Normal force Sine component of gravitational force

 2) At the top of the inclined plane the ball will have Maximum kinetic energy Equal amount of potential and kinetic energy Zero total energy Maximum potential energy

 3) As the angle of inclination increases The ball will roll down faster The motion of the ball is not affected The ball will roll down slowly The ball will move with uniform velocity

 4) Which two forces are responsible for rolling the ball Normal force and gravitational force Sine component of gravitational force and frictional force Normal force and frictional force Cosine component of gravitational force and frictional force

 5) The ball moving down on an inclined plane Is in uniform motion Is in free fall Is in non-uniformly accelerated motion Is in uniformly accelerated motion

 6) Whenever the surfaces in contact tend to move with respect to each other, the force of friction comes into play Irrespective of whether the objects chosen are solid, liquid or gaseous Only if one object is solid and the other is liquid Only if one of the two objects is solid Only if both objects are solid

 7) As a ball rolls down the incline, the distances covered by the ball in successive intervals Goes on decreasing by equal amounts Will remain the same Goes on changing by unequal amounts Goes on increasing by equal amounts

 8) A metronome is a device that produces pulse at regular intervals to help musicians play in time. The pulse in metronome is measured in BPM (beats-per-minute) which is a unit of Speed Frequency Time Power

 9) Identify the incorrect method to increase the speed of ball moving down an inclined plane Placing the inclined plane in Jupiter Increasing the inclination of the plane Decreasing the mass of the ball Reducing the friction on the path

 10) What is the acceleration of an object moving down an inclined plane mg sin θ g cos θ mg cos θ g sin θ
