An object launched in space having no driving power in an arbitrary direction is called:
Correct answer: D. Projectile
- A. Rocket
- B. Bullet
- C. Airship
- D. Projectile
Explanation
The correct answer is 'Projectile.' An object launched in space with no driving power and moving in an arbitrary direction is considered a projectile. Projectiles are solely influenced by gravity, following a trajectory path. Rockets and bullets have driving powers provided by engines or guns, respectively, making them incorrect choices. Airships do not exhibit the characteristics of objects moving under the sole influence of gravity, ruling out that option.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.

A car is moving with a uniform speed on a level road. Inside the car there is a balloon filled with helium and attached to a piece of string tied to the floor. The string is observed to be vertical. The car now takes a left turn maintaining the speed on the level road. The balloon in the car will:
The velocity of the projectile is increased by 2 %. If other factors remain unchanged, then what will be the percentage change in the maximum height attained?
A particle of mass 1 kg is projected at an angle of 30˚ with the horizontal with velocity v = 40 m/s. The change in linear momentum of the particle after time t = 1s will be: (g = 10 m/s2)
An object is thrown in the air with an initial velocity Vi and making an angle θ with the surface of the earth. The vertical component of its velocity after time t is given by:
The velocity V of a projectile can be found by the expression:
The angle θ that the projectile makes with the horizontal at any time t during its flight is given by:
