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 are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated due to gravity).

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 formula for the range of a projectile?

Back

Range (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

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

Back

The range is maximized at a launch angle of 45 degrees. Angles less than or greater than 45 degrees result in a shorter range.

Front

What is the maximum height of a projectile?

Back

The maximum height (H) can be calculated using H = (v^2 * sin^2(θ)) / (2g).

Front

What happens to the horizontal velocity of a projectile?

Back

The horizontal velocity remains constant throughout the motion, assuming no air resistance.

Front

What is the vertical velocity of a projectile at its peak?

Back

At the peak of its trajectory, the vertical velocity is 0 m/s.

Front

How long does it take for a projectile to reach its maximum height?

Back

Time to reach maximum height (t) = (v * sin(θ)) / g.

Front

What is the acceleration of a projectile in the vertical direction?

Back

The vertical acceleration is equal to -g (approximately -9.81 m/s²), directed downward.
