S1.20 Projectile Motion

Gravity

Air resistance

Magnetism

It helps us understand how objects move in the air and predict their paths.

It only applies to sports and is not useful in real life.

It is mainly about memorizing formulas without practical use.

It is only important for astronauts.

The velocity in the x-direction does not change.

The velocity in the y-direction increases due to gravity.

The resultant velocity is the vector sum of the horizontal and vertical motions.

The velocity in the x-direction increases over time.

Horizontal motion is constant velocity, vertical motion is accelerated by gravity.

Both horizontal and vertical motions are constant velocity.

Horizontal motion is accelerated by gravity, vertical motion is constant velocity.

Both horizontal and vertical motions are accelerated by gravity.

To describe and analyze acceleration using equations for objects launched without an angle

To memorize the equations for projectile motion

To solve only one practice question correctly

To focus on three dimensional motion only
