Forces & Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the formula for calculating acceleration?

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, which depends on the mass of the objects and the distance between them.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is a Free Body Diagram (FBD)?

Back

A Free Body Diagram is a graphical representation used to visualize the forces acting on an object.

Front

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

Back

According to Newton's Second Law, force (F) is equal to mass (m) times acceleration (a): F = m * a.

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 inertia?

Back

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