2D Motion - Summative

Front

To resolve a vector means to...

Back

find the x and y components of the vector.

Front

An object that is launched into the air is called a...

Back

Projectile.

Front

Two spheres of equal mass, A and B, are rolled off the edge of a 2.0 m high bench. Which ball will be in the air for the greater amount of time?

Back

They will be in the air for the same amount of time.

Front

What two factors affect the range of a projectile?

Back

Launch angle and Launch Velocity.

Front

A Macaque monkey sitting 12 m up in a tree throws a nut horizontally at 11 m/s. How long will it take the nut to hit the ground?

Back

1.56 s.

Front

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

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

Define horizontal motion in the context of projectile motion.

Back

Horizontal motion is the motion of an object along the horizontal axis, which is unaffected by gravity.

Front

What is the effect of launch angle on projectile motion?

Back

The launch angle determines the trajectory and range of the projectile; optimal angle for maximum range is 45 degrees.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
