Front

What is the horizontal motion of a projectile?

Back

The horizontal motion of a projectile is uniform, meaning it moves at a constant velocity without acceleration, assuming no air resistance.

Front

What is the vertical motion of a projectile?

Back

The vertical motion of a projectile is influenced by gravity, resulting in a downward acceleration of approximately 9.8 m/s².

Front

What is the formula for calculating the range of a projectile?

Back

Range (R) = (v₀² * sin(2θ)) / 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 velocity of a projectile at its peak height?

Back

At its peak height, the vertical velocity of a projectile is 0 m/s.

Front

How does the initial horizontal velocity affect the distance a projectile travels?

Back

A higher initial horizontal velocity results in a greater horizontal distance traveled by the projectile before it hits the ground.

Front

What is the time of flight for a projectile launched and landing at the same height?

Back

The time of flight is twice the time taken to reach the peak height.

Front

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

Back

The launch angle determines the shape of the projectile's trajectory and affects both the range and maximum height.

Front

What is the acceleration of a projectile in horizontal motion?

Back

The acceleration of a projectile in horizontal motion is 0 m/s², assuming no air resistance.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance reduces the range and height of a projectile compared to ideal conditions without air resistance.

Front

How do you calculate the maximum height of a projectile?

Back

Maximum height (H) = (v₀² * sin²(θ)) / (2g), where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.
