Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown or projected into the air, subject to the force of gravity and air resistance. It follows a curved path called a trajectory.

Front

What is the effect of mass on the time of flight of a projectile (neglecting air resistance)?

Back

The mass of a projectile has no effect on the time it is in the air when neglecting air resistance.

Front

When an object is projected horizontally, what is its initial vertical velocity?

Back

The initial vertical velocity of an object projected horizontally is 0 m/s.

Front

What angle should a projectile be launched to achieve maximum range?

Back

A projectile should be launched at an angle of 45 degrees to achieve the greatest range.

Front

What is the horizontal component of velocity for a projectile launched horizontally?

Back

The horizontal component of velocity remains constant throughout the projectile's flight, equal to the initial horizontal velocity.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s², acting downward on all objects in free fall.

Front

How does air resistance affect projectile motion?

Back

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

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the curved path it follows through the air, typically a parabola.

Front

What is the formula for the range of a projectile?

Back

The range R of a projectile launched at an angle θ with initial velocity v is given by R = (v² * sin(2θ)) / g, where g is the acceleration due to gravity.

Front

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

Back

Vertical motion is influenced by gravity and accelerates downward, while horizontal motion is constant and unaffected by gravity.
