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 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 acceleration due to gravity?

Back

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

Front

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

Back

The vertical component of velocity at the highest point is 0 m/s.

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.

Front

What is the effect of air resistance on projectile motion?

Back

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

Front

What is the time of flight for a projectile launched vertically?

Back

The time of flight (T) for a projectile launched vertically with initial velocity v is T = (2v) / g.

Front

What is the relationship between the launch angle and the range of a projectile?

Back

The range is maximized at a launch angle of 45 degrees.

Front

What is the formula for the maximum height of a projectile?

Back

The maximum height (H) of a projectile launched at an angle θ with initial velocity v is given by H = (v² * sin²(θ)) / (2g).

Front

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

Back

The vertical velocity decreases as the projectile rises due to the acceleration of gravity acting downward.
