Force & Motion Flashcard

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is produced when a force acts on a mass.

Front

What force pulls objects towards the center of the Earth?

Back

Gravity is the force that pulls objects towards the center of the Earth.

Front

How is force measured?

Back

Force is measured in Newtons.

Front

True or False: An object in motion remains in motion with the same speed and in the same direction unless acted upon by a balanced force.

Back

False. An object in motion remains in motion unless acted upon by an unbalanced force.

Front

How is acceleration measured?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

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

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

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

Front

What is the unit of mass?

Back

Mass is measured in kilograms (kg).

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity is speed in a given direction.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.
