Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following 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

Define displacement in the context of projectile motion.

Back

Displacement is the change in position of an object, measured as a straight line from the initial to the final position.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

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

Back

At its peak height, the vertical velocity of a projectile is zero.

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 acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.81 m/s², acting downward on all objects in free fall.

Front

If a projectile is launched at an angle, what are the two initial velocity components?

Back

The two initial velocity components are the horizontal component (Vx = V * cos(θ)) and the vertical component (Vy = V * sin(θ)).

Front

What is the formula for calculating the range of a projectile?

Back

The range R of a projectile launched at an angle θ with initial velocity V is given by R = (V² * sin(2θ)) / g.

Front

Explain the term 'trajectory' in projectile motion.

Back

Trajectory is the path that a projectile follows through space as a function of time.
