Flashcard 7

Front

What is speed in the context of motion?

Back

Speed is the distance traveled per unit of time, indicating how fast an object is moving.

Front

How does horizontal velocity affect the distance traveled by a projectile?

Back

The horizontal velocity determines how far the projectile will travel horizontally before hitting the ground, assuming no air resistance.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes the motion of an object. It can cause an object to slow down or stop when moving.

Front

What is balanced force?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no net force and no change in motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration (A) is calculated using the formula A = (final velocity - initial velocity) / time.

Front

How does mass affect the force required to maintain circular motion?

Back

The greater the mass of an object, the greater the force of friction required to keep it moving in a circular path.

Front

What is the significance of a position vs. time graph?

Back

A position vs. time graph shows how an object's position changes over time, allowing us to determine speed and direction of motion.

Front

What happens to the time of flight of a projectile when its horizontal velocity is doubled?

Back

The time of flight remains the same regardless of horizontal velocity, as it is determined by the height from which the projectile is thrown.

Front

What is the effect of increasing speed on the required friction force for circular motion?

Back

Increasing speed increases the required friction force to maintain circular motion, as friction must counteract the increased centripetal force.
