2D Motion - Summative

Front

What is the velocity of a baseball at the highest point when thrown straight up?

Back

0 m/s

Front

What is the shape of the pathway of a projectile called?

Back

Parabola

Front

If two spheres of equal mass are rolled off a 2.0 m high bench, will they be in the air for the same amount of time?

Back

Yes, they will be in the air for the same amount of time.

Front

In the expression '30° at 25 m/s', what does '30°' represent?

Back

Direction

Front

How long does it take for a nut thrown horizontally at 11 m/s from a height of 12 m to hit the ground?

Back

1.56 s

Front

What is the acceleration due to gravity near the Earth's surface?

Back

9.8 m/s²

Front

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

Back

Range = (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

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

What is the effect of air resistance on a projectile's motion?

Back

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

Front

What is the horizontal component of a projectile's motion?

Back

The horizontal component remains constant if air resistance is negligible.
