Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What is the vertical acceleration of a projectile?

Back

9.8 m/s², due to the force of gravity.

Front

What happens to the distance between drops of water falling from a faucet?

Back

As the drops fall, they get farther apart due to the acceleration of gravity.

Front

If two objects of different masses are dropped from the same height, which hits the ground first?

Back

Both objects hit the ground at the same time, regardless of their mass.

Front

What is the initial vertical velocity of a ball projected horizontally?

Back

0 m/s, as it has no vertical motion at the moment of projection.

Front

If a crayon is thrown straight up at 12 m/s, what is its speed when caught at the same height?

Back

12 m/s, as it returns to the same height with the same speed.

Front

What is the formula for the range of a projectile?

Back

Range = (initial velocity² * sin(2θ)) / g, where θ is the launch angle and g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

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

Front

What is the trajectory of a projectile?

Back

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

Front

What factors affect the time of flight of a projectile?

Back

Initial velocity, launch angle, and height from which it is launched.
