2 Dimensional Motion and Gravity Flashcard

Front

What is the relationship between Gravitational Force and Mass?

Back

Direct

Front

If a soccer ball rolls off a cliff horizontally at 12 m/s and takes 4 seconds to fall, how far does it fall?

Back

78 meters

Front

What is the definition of the trajectory of a projectile?

Back

The trajectory is the path the projectile takes as it goes through the air.

Front

If two projectiles are launched at different angles, which one hits the ground first?

Back

The one with the steeper angle (Projectile B).

Front

What is an example of a revolution?

Back

The Moon orbiting the Earth.

Front

Define 2D motion.

Back

Motion that occurs in a two-dimensional plane, involving both horizontal and vertical components.

Front

What is the formula for calculating the distance fallen under gravity?

Back

d = 0.5 * g * t^2, where g is the acceleration due to gravity (9.8 m/s²) and t is time.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

What is the difference between linear motion and projectile motion?

Back

Linear motion occurs in a straight line, while projectile motion involves an object moving under the influence of gravity and an initial velocity.

Front

What factors affect the trajectory of a projectile?

Back

Initial velocity, launch angle, and acceleration due to gravity.
