It's easy to roll the the basket ball than bowling ball
It is because bowling ball is solid spherical ball which will have less moment of inertia
its moment of inertia is given as
While for the hollow ball like basketball we know that moment of inertia is given as
so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.
So it is easy to roll basket ball then rolling ball
Answer:
THE KINETIC ENERGY OF THE SMALLER CHILD IS LESS THAN THAT OF THE BIGGER CHILD
Explanation: Kinetic energy is the energy that is exerted on a body that is in motion, kinetic energy is affected by both the mass of the object and the velocity of the object.
Mathematically,Kinetic energy is represented as follows;
K.E=1/2M
Where M represents the mass of the object in kilograms and V represents velocity of the moving object measured in meters per seconds.
The higher the weight of the object the higher the kinetic energy of the object which means the bigger child will have a higher kinetic energy than the smaller child.
