Final answer:
In projectile motion below 90 degrees on level ground, the constant force of gravity leads to a constant acceleration due to gravity with a magnitude of 9.80 m/s², impacting the object's velocity and displacement.
Step-by-step explanation:
When projecting an object below 90 degrees, assuming negligible air resistance and on level ground, the force produced is primarily the gravitational force, which causes an object to experience acceleration due to gravity. The three main components of this scenario are displacement, velocity, and acceleration. Using these, we can analyze projectile motion. In projectile motion:
- Acceleration is never zero, as the object is always under the influence of gravity, which imparts a constant acceleration due to gravity denoted by the symbol g, with an average value of 9.80 m/s².
- Acceleration is in the same direction as a component of velocity during the object's ascent when both are directed upward or during descent when both are directed downward.
- Acceleration is opposite in direction to a component of velocity at the peak of the projectile's trajectory, where the vertical component of velocity is zero but acceleration due to gravity is still acting downward.
Therefore, when projecting an object on level ground below 90 degrees, what is produced is a force due to gravity leading to constant acceleration, not just weight, velocity, or acceleration as standalone concepts.
