Acceleration due to gravity on hill is less than that on the surface of earth (due to altitude effect ), so the ball will bounce higher on hills than on planes .

Collision is an event in which two or more bodies exert forces on each other for a relatively short time. Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this.
Examples:-
An insect touches its antenna to the leaf of a plant. The antenna is said to collide with leaf.
When a boxer throws a punch, his fist is said to collide with the opponent's face

Torque: It is a measure of the force that can cause an object to rotate about an axis.
Force causes an object to accelerate in linear kinematics, torque causes an object to acquire angular acceleration. Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis.

The more mass an object has, the greater its gravitational pull on other objects. The most massive object in the solar system is the sun because the amount of gravity exerted by the sun is so much more than the Earth’s gravitational pull, the Earth is forced into an orbit around the sun. The sun’s gravity pulls the Earth toward it and makes it revolving.

Rainbow is a combination of refraction, dispersion and total internal reflection of sunlight. In sky, prism like objects are needed for the dispersion of light. After rainfall, tiny water drops suspended in air act as prisms. The rainbow's appearance is caused by dispersion of sunlight as it is refracted by (approximately spherical) raindrops.
The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop.Their colors come from raindrops that reflect sunlight, breaking white sunlight into colors .
Sunlight is made up of many wavelengths so that makes us see the colors of the rainbow.When the light enters the water, it bends causing its shape.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism.

A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
A projectile is any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown. (This is an informal definition.) The path of a projectile is called its trajectory. Some examples of projectiles include a baseball that has been pitched, batted, or thrown .
