Projectile Motion

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 happens to the horizontal velocity of a projectile as it travels along the curved path?

Back

The horizontal velocity stays the same.

Front

If a projectile is launched with a horizontal speed of 54 m/s, what will its horizontal speed be after 2 seconds, ignoring air resistance?

Back

The horizontal speed will still be 54 m/s.

Front

What is the trajectory of a projectile?

Back

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

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, affecting its speed and trajectory.

Front

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

Back

The optimal angle for maximum range is 45 degrees. Launching at this angle maximizes the horizontal distance traveled.

Front

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

Back

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

Front

How long does it take for a projectile to hit the ground if thrown horizontally from a height of 60 meters?

Back

It takes approximately 3.5 seconds to hit the ground.

Front

What is the vertical motion of a projectile influenced by?

Back

The vertical motion is influenced by gravity, which causes the projectile to accelerate downwards.
