What is the formula to calculate 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 (approximately 9.81 m/s²).

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

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 launch angle, and g is the acceleration due to gravity.

Front

Define horizontal range in projectile motion.

Back

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

Front

What is the significance of the angle of projection in projectile motion?

Back

The angle of projection determines the trajectory shape, maximum height, and horizontal range of the projectile. An angle of 45 degrees typically provides the maximum range.

Front

What is the role of gravity in projectile motion?

Back

Gravity acts as a constant downward force that affects the vertical motion of the projectile, causing it to accelerate downwards at approximately 9.81 m/s².

Front

How does initial velocity affect the trajectory of a projectile?

Back

A higher initial velocity increases both the maximum height and the horizontal range of the projectile, allowing it to travel further and higher.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

What is the formula for calculating the horizontal distance traveled by a projectile?

Back

The horizontal distance (d) can be calculated using the formula: d = v * cos(θ) * T, where v is the initial velocity, θ is the launch angle, and T is the time of flight.

Front

Explain the concept of trajectory in projectile motion.

Back

The trajectory is the path that a projectile follows through space, which is typically a parabolic shape due to the influence of 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 maximum height compared to ideal conditions without air resistance.
