Back

Friction.

Front

What is the name of the force that causes an object to move in a circle?

Back

Centripetal force.

Front

What happens to the inertia of an object as its mass increases?

Back

The greater its mass, the greater its inertia.

Front

According to Newton’s third law of motion, how does the strength of a reaction force compare to the strength of the action force?

Back

They are equal to each other.

Front

How does the acceleration of a 1-kg object compare to that of a 2-kg object?

Back

The 1-kg object has more acceleration because it has less mass.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
