Projectile Motion, Circular Motion, and Relative Velocity

Front

What is the horizontal acceleration of a projectile?

Back

0 m/s²

Front

The path followed by a projectile is also known as its:

Back

trajectory

Front

What is the direction of the acceleration at point B, if the ball is revolving clockwise?

Back

left

Front

At what point is v_x = 0 m/s?

Back

None of these points

Front

A train is moving at a velocity of 15 m/s East. A passenger at the back of a train throws a baseball with a speed of 15 m/s West. What is the velocity of the baseball relative to the ground?

Back

0 m/s

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

Horizontal and vertical components.

Front

What is the acceleration due to gravity?

Back

Approximately 9.8 m/s² downward.

Front

What is the formula for the range of a projectile?

Back

Range = (v₀² * sin(2θ)) / g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is circular motion?

Back

Circular motion is the motion of an object moving along a circular path.
