Projectile Motion Review Flashcard

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 and vertical motion. Horizontal motion is uniform, while vertical motion is influenced by gravity.

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 near the Earth's surface.

Front

What is the vertical displacement of a projectile at the peak of its trajectory?

Back

At the peak of its trajectory, the vertical displacement is at its maximum, but the vertical velocity is 0 m/s.

Front

How does the horizontal velocity of a projectile change during its flight?

Back

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

Front

What happens to the total distance a projectile travels as it falls?

Back

The total distance increases at a nonconstant rate due to the influence of gravity.

Front

What is the formula for calculating the time of flight for a projectile?

Back

The time of flight can be calculated using the formula: t = (2 * v₀ * sin(θ)) / g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the significance of the highest point in projectile motion?

Back

At the highest point, the vertical component of the velocity is 0 m/s, and the projectile starts to descend.

Front

How do you calculate the range of a projectile?

Back

The range can be calculated using the formula: R = (v₀² * sin(2θ)) / g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration 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.
