Projectile Motion and Circular Motion Flashcard

Front

What is the formula for tangential velocity in circular motion?

Back

Front

How do you calculate the horizontal distance traveled by a projectile?

Back

The horizontal distance (d_x) can be calculated using the formula: d_x = V_ix * t, where V_ix is the initial horizontal velocity and t is the time of flight.

Front

What happens to the vertical velocity of a projectile as it ascends?

Back

The vertical velocity of a projectile decreases as it goes up due to the acceleration of gravity acting downwards.

Front

What does it mean that acceleration is independent of mass in free fall?

Back

It means that all objects, regardless of their mass, experience the same acceleration due to gravity when falling.

Front

If an object is projected horizontally from a height, how does its fall time compare to an object dropped vertically?

Back

The time it takes for both objects to hit the ground is the same, regardless of the horizontal motion.

Front

What is the acceleration due to gravity near the Earth's surface?

Back

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

Front

Define projectile motion.

Back

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

Front

What is the difference between vertical and horizontal motion in projectile motion?

Back

Vertical motion is influenced by gravity, causing acceleration downwards, while horizontal motion is constant if air resistance is negligible.

Front

What is the significance of the range in projectile motion?

Back

The range is the horizontal distance a projectile travels before hitting the ground, determined by initial velocity and launch angle.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.
