Front

What is the force that slows objects down when they rub against each other?

Back

Friction

Front

What is defined as a push or pull between objects?

Back

Force

Front

What is the term for speeding up caused by unbalanced forces?

Back

Acceleration

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the effect of balanced forces on an object?

Back

The object remains at rest or continues to move at a constant speed.

Front

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

Back

Acceleration is directly proportional to the net force and inversely proportional to the mass.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)
