Projectile Motion Concepts

When one baseball is dropped and another is shot horizontally from the same height at the same time, which ball hits the ground first?

• The dropped ball

• The shot ball

• Both balls hit at the same time

• It depends on how fast the ball is shot

What happens to the vertical speed of a ball as it falls towards the ground?

• It stays the same

• It decreases

• It increases

• It first increases then decreases

The acceleration due to gravity near Earth's surface is approximately 9.8 meters per second squared. In which direction does this acceleration always act?

• Upwards

• Downwards

• Sideways

• It changes direction

If we ignore air resistance, what happens to the horizontal speed of a ball after it is shot horizontally?

• It increases

• It decreases

• It stays the same

• It changes direction

If you throw a ball straight out from a cliff, and at the same time drop another ball from the same height, which ball will hit the ground first?

• The thrown ball.

• The dropped ball.

• Both balls will hit the ground at the same time.

• It depends on how fast the ball was thrown.

When a baseball is hit into the air at an angle, what two types of motion can we think of it having at the same time?

• Spinning motion and rolling motion.

• Up and down motion, and side to side motion.

• Fast motion and slow motion.

• Straight motion and curved motion.

What is an object called if it is only moving under the influence of gravity?

• A rocket.

• A glider.

• A projectile.

• A balloon.

In projectile motion, how do the horizontal and vertical movements relate to each other?

• They always happen at the same speed.

• They are connected and affect each other a lot.

• They are separate and do not affect each other.

• One stops when the other starts.
