Unit 3 - Two-Dimensional Motion: Activity 1 (Flashcardizz)

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = ma.

Front

What does it mean that velocity depends on the observer's location?

Back

This concept refers to the principle of relativity, which states that the measurements of time and space can vary depending on the relative motion of the observer.

Front

Complete the statement: Newton's third law states that any action will have a(n) _______ and ______ reaction.

Back

Equal and opposite.

Front

How do you calculate the acceleration of an object moving in a circle?

Back

Acceleration can be calculated using the formula a = v²/r, where v is the velocity and r is the radius of the circle.

Front

If a projectile is launched horizontally, how do you calculate its range?

Back

The range can be calculated using the formula Range = horizontal velocity × time of flight.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

What is the significance of the net force in motion?

Back

The net force is the vector sum of all forces acting on an object, determining its acceleration and direction of motion.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, as mass increases, acceleration decreases for a given force, indicating an inverse relationship.
