chp 5 projectile motion flashcardizz review

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What is the formula to calculate the vertical distance fallen by an object in free fall?

Back

d = (1/2)gt², where d is the distance, g is the acceleration due to gravity (approximately 9.81 m/s²), and t is the time in seconds.

Front

What happens to the velocity of a ball thrown straight up at its maximum height?

Back

At its maximum height, the ball's velocity is at its minimum (0 m/s) before it starts to fall back down.

Front

What are vectors?

Back

Vectors are quantities that have both magnitude and direction, such as velocity, acceleration, and force.

Front

What are scalars?

Back

Scalars are quantities that have only magnitude and no direction, such as speed, mass, and temperature.

Front

How long does it take for an object to fall from a height of 45 m?

Back

Using the formula t = √(2d/g), it takes approximately 3.0 seconds to hit the ground.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity (g) is approximately 9.81 m/s² near the surface of the Earth.

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the path it follows through the air, 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 a projectile, reducing its range and altering its trajectory compared to ideal projectile motion without air resistance.
