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 of projectile motion are horizontal motion and vertical motion. These components are independent of each other.

Front

How do you calculate the vertical component of velocity?

Back

The vertical component of velocity (Vy) can be calculated using the formula: Vy = V * sin(θ), where V is the initial velocity and θ is the angle of projection.

Front

How do you calculate the horizontal component of velocity?

Back

The horizontal component of velocity (Vx) can be calculated using the formula: Vx = V * cos(θ), where V is the initial velocity and θ is the angle of projection.

Front

What is the formula for the time of flight of a projectile?

Back

The time of flight (T) can be calculated using the formula: T = (2 * V * sin(θ)) / g, where V is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the maximum height of a projectile?

Back

The maximum height (H) can be calculated using the formula: H = (V² * sin²(θ)) / (2 * g), where V is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.

Front

What is the range of a projectile?

Back

The range (R) of a projectile can be calculated using the formula: R = (V² * sin(2θ)) / g, where V is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.

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 compared to ideal projectile motion without air resistance.

Front

How does the angle of projection affect the range of a projectile?

Back

The angle of projection affects the range; a 45° angle typically provides the maximum range for a given initial velocity in ideal conditions.

Front

What is the significance of the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity remains constant throughout the motion (in the absence of air resistance), determining how far the projectile travels horizontally.
