Projectile Motion 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. They are independent of each other.

Front

What is the effect of gravity on a projectile?

Back

Gravity acts downward on a projectile, causing it to accelerate downwards at approximately 9.81 m/s².

Front

What is the initial velocity in projectile motion?

Back

Initial velocity (v₀) is the speed at which a projectile is launched, which can be broken down into horizontal (v₀x) and vertical (v₀y) components.

Front

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

Back

The angle of launch affects the range; typically, a launch angle of 45 degrees maximizes the horizontal distance traveled.

Front

What is the formula for the range of a projectile?

Back

Range (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 time of flight in projectile motion?

Back

Time of flight is the total time a projectile is in the air, which can be calculated using the formula: T = (2 * v₀y) / g.

Front

What happens to the vertical velocity of a projectile at its peak?

Back

At the peak of its trajectory, the vertical velocity (v₁y) of a projectile is 0 m/s.

Front

What is the horizontal velocity of a projectile?

Back

The horizontal velocity remains constant throughout the flight of the projectile, as there are no horizontal forces acting on it (ignoring air resistance).

Front

What is the significance of the trajectory of a projectile?

Back

The trajectory is the path that a projectile follows, which is typically a parabolic shape due to the influence of gravity.
