Projectile Motion Basics

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 happens to the velocity of a projectile at the peak of its trajectory?

Back

At the peak of its trajectory, the vertical component of the projectile's velocity is zero, meaning it has the least velocity at this point.

Front

What is free fall?

Back

Free fall is the motion of an object when the only force acting on it is gravity, causing it to accelerate downwards.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is the shape of the trajectory of a projectile?

Back

The trajectory of a projectile is a parabola.

Front

What is the relationship between time of flight and maximum height in projectile motion?

Back

The time of flight is directly related to the maximum height; the longer the time of flight, the higher the maximum height.

Front

What is the final velocity of a projectile at its highest point?

Back

The final velocity at the highest point of a projectile's trajectory is 0 m/s in the vertical direction.

Front

What forces act on a projectile in motion?

Back

The only force acting on a projectile in motion (after it is launched) is gravity.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

What is the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity remains constant throughout the projectile's flight, assuming no air resistance.
