Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is a form of motion experienced by an object or particle that is thrown near the earth's surface and moves along a curved path under the action of gravity and its initial velocity.

Front

What are the two components of projectile motion?

Back

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

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 * V₀ * sin(θ)) / g, where V₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What happens to the vertical component of velocity at maximum height?

Back

At maximum height, the vertical component of velocity becomes zero.

Front

What is the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity remains constant throughout the projectile's flight, as there is no horizontal acceleration (ignoring air resistance).

Front

How do you calculate the maximum height of a projectile?

Back

The maximum height (H) can be calculated using the formula: H = (V₀² * (sin(θ))²) / (2g), where V₀ 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 = (V₀² * sin(2θ)) / g.

Front

What is the effect of launch angle on the range of a projectile?

Back

The range of a projectile is maximized at a launch angle of 45 degrees, assuming no air resistance.

Front

What is the significance of the x-component of velocity in projectile motion?

Back

The x-component of velocity is constant and determines how far the projectile travels horizontally during its flight.

Front

What is the significance of the y-component of acceleration in projectile motion?

Back

The y-component of acceleration is equal to -g (approximately -9.81 m/s²) and affects the vertical motion of the projectile.
