Trajectory Of Projectile
1. What is a projectile?
- An object thrown into space upon which the only acting force is gravity
- An object that generates its own thrust in the air
- An object that moves in a straight line without acceleration
- A stationary object in equilibrium
2. What is a trajectory?
- The horizontal distance traveled before impact
- The maximum height reached by an object
- The straight-line distance between two points
- The path followed by a projectile under the influence of gravity
3. What role does friction play in a projectile’s trajectory?
- Friction acts against motion, reducing range and height
- Friction increases the speed of the projectile
- Friction has no effect on trajectory
- Friction provides an upward force
4. How does the formula for projectile motion change when friction is removed?
- The motion becomes circular
- The standard equations of motion under constant acceleration apply without air resistance
- The projectile comes to a stop immediately
- The motion becomes irregular and unpredictable
