Projectile Motion and Acceleration Concepts

Front

What describes the horizontal motion of a projectile in the absence of air resistance?

Back

Constant velocity.

Front

What happens to the gravitational force between two planets as they move farther apart?

Back

The gravitational force decreases.

Front

Is there gravity on the International Space Station?

Back

Yes, there is gravity on the International Space Station.

Front

If two projectiles are launched from different heights, which one will hit the ground first?

Back

The projectile launched from the lower height will hit the ground first.

Front

What happens to the gravitational attraction between a comet and the sun as the comet approaches the sun?

Back

The gravitational attraction gets stronger.

Front

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

Back

Approximately -9.8 m/s².

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity.

Front

What are the two components of projectile motion?

Back

Horizontal motion and vertical motion.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion, reducing the range and height of the projectile.

Front

What is the trajectory of a projectile?

Back

The path that a projectile follows through space, typically a parabolic shape.
