AP Flashcard Projectile motion

Front

What is the acceleration of a projectile just after it is thrown upwards at an angle?

Back

The acceleration is downwards at 9.8 m/s² due to gravity.

Front

What are the vertical components of velocity and acceleration for a projectile at its highest point?

Back

At the highest point, the vertical component of velocity is 0 m/s, but the acceleration is still g (9.8 m/s² downwards).

Front

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

Back

The horizontal velocity remains constant if air friction is negligible.

Front

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

Back

Range = (V₀² * sin(2θ)) / g, where V₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

How does the height of a table affect the distance a projectile lands from the edge?

Back

The greater the height, the further the projectile will land from the edge, assuming horizontal launch.

Front

What is the relationship between the initial speed of two projectiles and their speed upon hitting the ground?

Back

The projectile with the higher initial speed will have a greater speed upon impact, regardless of the height.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance decreases the range and alters the trajectory of the projectile.

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity and air resistance.

Front

What is the trajectory of a projectile?

Back

The trajectory is the path that a projectile follows, typically a parabolic shape in the absence of air resistance.

Front

What is the significance of the angle of projection in projectile motion?

Back

The angle of projection determines the shape of the trajectory and the range of the projectile.
