Study Notes
Projectile Motion
- The curved path of a projectile is called a trajectory.
- The horizontal distance traveled by a projectile is called the range.
- A projectile is any object dropped, thrown, or set into motion through space.
- Gravity is the force that acts in the y-direction causing a projectile to travel in a parabolic arc.
- The path traced by a projectile affected by air resistance is asymmetric.
Momentum and Collisions
- Momentum is defined as the product of mass and velocity.
- Impulse is defined as the product of the net force and the time interval over which the force acts.
- An elastic collision is a type of collision that conserves both momentum and kinetic energy.
- A perfectly inelastic collision is a type of collision where the two colliding objects stick together after the collision, resulting in their final velocities being the same. Momentum is conserved in this type of collision.
- An inelastic collision is a type of collision where momentum is conserved but kinetic energy is not.
Units
- The unit of momentum is kg.m/s.
- The unit of mass is kg.
- The unit of impulse is N.s.
- The unit of force is N.
- The unit of range and height is m.
- The unit of time is s.
- The unit of velocity is m/s.
Other
- Projectile motion combines straight-line motion with free fall.
