Projectile Motion Review

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 constant, while vertical motion is affected by gravity.

Front

What is the formula for calculating the maximum height of a projectile?

Back

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

Front

What is the acceleration of a projectile in the vertical direction?

Back

The acceleration of a projectile in the vertical direction is constant and equal to -9.8 m/s² (downward) due to gravity.

Front

At the highest point of a projectile's trajectory, what is the vertical velocity?

Back

The vertical velocity at the highest point is 0 m/s.

Front

How does the horizontal velocity of a projectile change during its flight?

Back

The horizontal velocity remains constant throughout the flight if air resistance is negligible.

Front

What is the time of flight for a projectile launched at an angle?

Back

The time of flight can be calculated using the formula T = (2 * v * sin(θ)) / g, where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the range of a projectile?

Back

The range is the horizontal distance traveled by the projectile and can be calculated using the formula R = (v^2 * sin(2θ)) / g.

Front

What factors affect the range of a projectile?

Back

The range is affected by the initial velocity, launch angle, and the height from which it is launched.

Front

What happens to the time of flight if the launch angle is increased?

Back

Increasing the launch angle generally increases the time of flight, up to a maximum angle of 45 degrees for maximum range.
