Projectile Motion

Front

What is the horizontal component of velocity (v_x) in projectile motion?

Back

The horizontal component of velocity (v_x) remains constant throughout the motion, as there is no horizontal acceleration.

Front

At what point in projectile motion is the vertical component of velocity (v_y) equal to zero?

Back

The vertical component of velocity (v_y) is equal to zero at the peak of the projectile's trajectory.

Front

What happens to the horizontal velocity (v_x) of a projectile as it moves through the air?

Back

The horizontal velocity (v_x) remains constant, assuming no air resistance.

Front

What is the effect of gravity on the vertical motion of a projectile?

Back

Gravity causes the vertical component of velocity (v_y) to decrease until it reaches zero at the peak, and then it increases again as the projectile falls.

Front

If two objects are dropped from the same height but with different horizontal velocities, which will hit the ground first?

Back

Both objects will hit the ground at the same time, as the time of fall is independent of horizontal velocity.

Front

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

Back

The range of a projectile is maximized at a projection angle of 45 degrees, assuming no air resistance.

Front

What is the formula for the range of a projectile launched at an angle?

Back

The range (R) can be calculated using the formula R = (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 is the relationship between the time of flight and the vertical motion of a projectile?

Back

The time of flight is determined by the initial vertical velocity and the height from which the projectile is launched.

Front

What is the significance of the initial velocity in projectile motion?

Back

The initial velocity determines both the range and the maximum height of the projectile.

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is a parabolic path determined by its initial velocity and the effects of gravity.
