Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is a form of motion experienced by an object or particle that is thrown near the earth's surface and moves along a curved path under the action of gravity and air resistance.

Front

What are the two components of projectile motion?

Back

The two components of projectile motion are horizontal motion and vertical motion.

Front

What is the effect of air resistance on projectile motion?

Back

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

Front

What is the formula for 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 = (v^2 * sin(2θ)) / g, where g is the acceleration due to gravity.

Front

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

Back

The range is maximized at a launch angle of 45 degrees in the absence of air resistance.

Front

What is the maximum height of a projectile?

Back

The maximum height H of a projectile launched at an angle θ with initial velocity v is given by H = (v^2 * (sin(θ))^2) / (2g).

Front

What is the horizontal acceleration of a projectile?

Back

The horizontal acceleration of a projectile is 0 m/s², assuming no air resistance.

Front

What happens to the speed of a projectile when it reaches the same height from which it was launched?

Back

The speed of the projectile will be the same as its initial speed when it returns to the same height, assuming no air resistance.

Front

Does the mass of an object affect the time it takes to fall?

Back

No, the mass of an object does not affect the time it takes to fall; all objects fall at the same rate in a vacuum.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity (g) is approximately 9.81 m/s² near the surface of the Earth.
