Key Concepts

Projectile Motion

Projectile motion involves the movement of an object under the influence of gravity, where the only force acting is the gravitational force. In vertical projectile motion, the object is thrown upward and then decelerates due to gravity until it reaches its maximum height before accelerating downward.

Uniform Acceleration

Uniform acceleration refers to motion where the acceleration remains constant over time. In the case of vertical projectile motion without air resistance, the only acceleration present is gravitational acceleration, which remains constant throughout the flight of the ball.

Velocity-Time Graph in Kinematics

The velocity-time graph is a graphical representation of an object's velocity as a function of time. For motion with constant acceleration, such as vertical projectile motion without air resistance, the graph is a straight line. The slope of this line represents the constant acceleration, which in this case is the acceleration due to gravity.

Gravitational Acceleration

Gravitational acceleration is the acceleration due to the force of gravity. On Earth, it is approximately 9.8 m/s² downward. In a vertical projection scenario where air resistance is ignored, this constant gravitational acceleration causes the object's upward velocity to decrease linearly until it reaches zero at the peak of its trajectory, after which the velocity increases (in the negative direction) linearly.
