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 does the letter 'd' represent in projectile motion equations?

Back

In projectile motion, 'd' typically represents the horizontal range of the projectile, not a vertical distance.

Front

What is the significance of air resistance in projectile motion?

Back

Air resistance affects the motion of a projectile by slowing it down, but in ideal projectile motion problems, it is often neglected.

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

At what point in projectile motion is the horizontal velocity (vx) zero?

Back

The horizontal velocity (vx) is never zero during projectile motion unless the projectile has landed.

Front

What is the vertical component of velocity at the peak of the trajectory?

Back

At the peak of the trajectory, the vertical component of velocity (vy) is zero.

Front

How does the angle of launch affect the range of a projectile?

Back

The angle of launch affects the range; a launch angle of 45 degrees typically provides the maximum range for a given initial velocity.

Front

What is the relationship between time of flight and range in projectile motion?

Back

The time of flight is directly related to the range; a longer time of flight generally results in a greater range, assuming constant initial velocity.

Front

What is the resultant velocity in projectile motion?

Back

The resultant velocity (Vo) is the vector sum of the horizontal (Vox) and vertical (Voy) components of velocity.

Front

What happens to the vertical motion of a projectile?

Back

The vertical motion of a projectile is influenced by gravity, causing it to accelerate downwards at a rate of approximately 9.81 m/s².
