Forces and Newton's Laws

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion, either by accelerating, decelerating, or changing direction.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma)

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its motion.

Front

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is gravitational force?

Back

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

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object when it is in contact with another surface.

Front

How do you calculate the net force acting on an object?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).
