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 constant, while vertical motion is affected by gravity.

Front

What is the acceleration due to gravity?

Back

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

Front

How does vertical velocity change during projectile motion?

Back

Vertical velocity changes continuously due to the acceleration of gravity acting on the object.

Front

What happens to the horizontal velocity of a projectile?

Back

The horizontal velocity remains constant if air resistance is negligible.

Front

If two objects are dropped from the same height, how do their masses affect the time it takes to hit the ground?

Back

The mass of the objects does not affect the time to hit the ground; both will hit at the same time.

Front

What is the shape of the trajectory of a projectile?

Back

The trajectory of a projectile is a parabola.

Front

What factors affect the range of a projectile?

Back

The range is affected by the initial velocity, launch angle, and height of the launch.

Front

What is the optimal angle for maximum range in projectile motion?

Back

The optimal angle for maximum range is 45 degrees.

Front

How does air resistance affect projectile motion?

Back

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