Projectile Motion A projectile, the vertical velocity of a projectile , the mass of a projectile. Mark only one oval. scalar, scalar, vector vector, vector, scalar vector, scalar, vector scalar, vector, scalar Identify the following quantities as scalar or vector:the acceleration of a spoints

The correct answer is **vector, scalar, vector**.<br /><br />Here's the breakdown:<br /><br />* **The acceleration of a projectile (vector):** Acceleration has both magnitude (how much the speed is changing) and direction (whether it's speeding up, slowing down, or changing direction). In projectile motion, acceleration is typically due to gravity, which acts downwards.<br /><br />* **The vertical velocity of a projectile (scalar):** Velocity has both magnitude (speed) and direction. Therefore, *velocity* is a vector. However, the question asks specifically for the *vertical velocity*. While we often treat upwards as positive and downwards as negative to indicate direction, the question is likely probing for an understanding that the *speed* in the vertical direction is a scalar quantity. If the question had asked simply for "velocity," the answer would be vector.<br /><br />* **The mass of a projectile (scalar):** Mass only has magnitude (how much matter is present). It doesn't have a direction associated with it.<br />
