Physics Unit 1.3 - Projectile motion

Front

What is a projectile?

Back

A projectile is any object that is thrown, dropped, fired, or otherwise propelled, and is subject to the influence of gravity and air resistance.

Front

Which of the following is NOT considered a projectile?

Back

A cannon ball rolling down a slope.

Front

What are the components of projectile motion?

Back

Projectile motion can be broken down into horizontal and vertical components.

Front

What is the horizontal acceleration of a projectile in the absence of air resistance?

Back

0 m/s².

Front

What happens to the vertical velocity of a projectile as it ascends?

Back

The vertical velocity decreases due to the acceleration of gravity acting downward.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance can alter the trajectory and reduce the range of a projectile.

Front

What is the relationship between the angle of projection and the range of a projectile?

Back

The range is maximized at a projection angle of 45 degrees in the absence of air resistance.

Front

How does the horizontal component of velocity behave in projectile motion?

Back

The horizontal component of velocity remains constant in the absence of horizontal acceleration.

Front

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

Back

Range = (initial velocity^2 * sin(2 * angle)) / g, where g is the acceleration due to gravity.

Front

What is the significance of the initial velocity in projectile motion?

Back

The initial velocity determines the maximum height and range of the projectile.
