Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion and vertical motion. Horizontal motion is uniform, while vertical motion is influenced by gravity.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s², acting downwards on all objects in free fall.

Front

How does the height from which a projectile is launched affect its time of flight?

Back

The higher the launch height, the longer the time of flight, as it takes more time to fall to the ground.

Front

What is the shape of the trajectory of a projectile?

Back

The trajectory of a projectile is a parabola.

Front

What happens to the vertical velocity of a projectile as it rises?

Back

The vertical velocity decreases as the projectile rises due to the acceleration of gravity acting downwards.

Front

What happens to the horizontal velocity of a projectile in the absence of air resistance?

Back

The horizontal velocity remains constant throughout the motion.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

What is the formula for the range of a projectile launched at an angle?

Back

The range R is given by R = (v² * sin(2θ)) / g, where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the maximum height of a projectile?

Back

The maximum height H can be calculated using H = (v² * sin²(θ)) / (2g), where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.
