unit 3 Projectile 2D Motion

Front

Can you use information about the x-axis to solve for variables on the y-axis?

Back

No, the x-axis and y-axis represent independent and dependent variables respectively in projectile motion.

Front

Does mass affect how fast an object falls?

Back

False, all objects fall at the same rate regardless of mass in a vacuum.

Front

If Lemming A (6lbs) and Lemming B (0.5lbs) run off a cliff, which will hit the ground first?

Back

Both at the same time because gravity affects them equally.

Front

What happens to the horizontal velocity of a ball when it rolls off a table?

Back

The horizontal velocity stays the same (V_ix = V_fx).

Front

What angle should an object be launched at to achieve the farthest distance/range?

Back

An object launched at 45 degrees will give you the farthest distance/range.

Front

What is the effect of gravity on projectile motion?

Back

Gravity acts downward, affecting the vertical motion of the projectile.

Front

What are the two components of projectile motion?

Back

Horizontal motion and vertical motion.

Front

What is the formula for the range of a projectile launched at an angle?

Back

Range = (V^2 * sin(2θ)) / g, where V is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the acceleration of a projectile in the horizontal direction?

Back

The acceleration in the horizontal direction is zero (ignoring air resistance).

Front

What is the maximum height of a projectile?

Back

The maximum height is reached when the vertical velocity is zero.
