2D Motion Flashcardziz

Front

What is 2D motion?

Back

2D motion refers to the movement of an object in a two-dimensional plane, involving both horizontal and vertical components.

Front

What is the formula for the range of a projectile?

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 happens to the vertical velocity of a projectile as it rises?

Back

The vertical velocity decreases due to the acceleration of gravity until it reaches the peak of its trajectory.

Front

What is the acceleration of a projectile at the peak of its trajectory?

Back

The acceleration is still -9.81 m/s² downward due to gravity, even though the vertical velocity is zero.

Front

How does launch angle affect the range of a projectile?

Back

The optimal launch angle for maximum range (without air resistance) is 45 degrees.

Front

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

Back

Horizontal and vertical motions are independent of each other; horizontal motion is constant while vertical motion is affected by gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance decreases the range and alters the trajectory of the projectile compared to ideal conditions.

Front

What is the significance of the term 'projectile'?

Back

A projectile is any object that is thrown into the air with an initial velocity and is subject to gravitational force.

Front

What is the vertical component of velocity at the highest point of a projectile's path?

Back

The vertical component of velocity is zero at the highest point of the projectile's path.

Front

What is the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity remains constant throughout the motion, assuming no air resistance.
