2D Motion - Vocabulary

Front

What is 2D motion?

Back

2D motion refers to the movement of an object in a two-dimensional plane, involving both horizontal and vertical components.

Front

What is acceleration in 2D motion?

Back

Acceleration is the rate of change of velocity of an object in a specific direction.

Front

What is the direction of acceleration for an object moving in a circular path?

Back

The acceleration is always directed towards the center of the circular path.

Front

Define 'tangent' in relation to a circle.

Back

A tangent is a line that touches the circle at exactly one point.

Front

What is a projectile?

Back

A projectile is an object that is thrown into the air with an initial velocity and is subject to gravitational force.

Front

What shape does a projectile follow when launched at an angle?

Back

A projectile follows a parabolic path when launched at an angle.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and the Moon.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
