Back

Inertia

Front

What do we call the state when the speed of an object remains the same, without increasing or decreasing?

Back

Constant speed

Front

What is the rate at which an object changes its speed or direction, including speeding up, slowing down, or changing direction?

Back

Acceleration

Front

What is the force that occurs when one object rubs against another?

Back

Friction

Front

What law states that when an unbalanced force acts upon an object, it changes its speed and direction?

Back

Newton's 2nd Law of Motion

Front

What is the term for the force that opposes the motion of an object?

Back

Friction

Front

What is the relationship between mass, acceleration, and force according to Newton's 2nd Law?

Back

Force = Mass x Acceleration

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant speed in a straight line.

Front

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

Back

Newton (N)
