Projectile Motion

Front

What is 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. It follows a curved path called a trajectory.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s² near the surface of the Earth.

Front

What is the formula for the vertical velocity of a projectile at time t?

Back

The vertical velocity V_y at time t is given by V_y = V_0y - gt, where V_0y is the initial vertical velocity and g is the acceleration due to gravity.

Front

What is the optimal angle for maximum range in projectile motion?

Back

The optimal angle for maximum range in projectile motion, in the absence of air resistance, is 45°.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory compared to motion in a vacuum.

Front

What is the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity remains constant throughout the motion, as there is no horizontal acceleration in ideal conditions.

Front

What is the maximum height in projectile motion?

Back

The maximum height is the highest point reached by the projectile, where the vertical velocity is zero.

Front

What is the time of flight in projectile motion?

Back

The time of flight is the total time the projectile is in the air, which can be calculated using the formula t = (2V_0y)/g.

Front

What is the range of a projectile?

Back

The range is the horizontal distance traveled by the projectile from the launch point to the landing point.

Front

What factors affect the range of a projectile?

Back

The range of a projectile is affected by the initial velocity, launch angle, and height of launch.
