Newton's Laws of Motion Review

Front

What happens to an object when unbalanced forces act on it?

Back

The object will move in the direction of the larger force.

Front

State Newton's Second Law of Motion.

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

What does a position vs. time graph indicate if the object is accelerating?

Back

The object is speeding up.

Front

What is the net force when all forces acting on an object are balanced?

Back

0 N, no direction.

Front

What must be applied to an object to change its state of motion?

Back

An unbalanced force.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the relationship between acceleration and net force?

Back

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

Front

What does it mean for an object to be in equilibrium?

Back

The net force acting on the object is zero, resulting in no acceleration.
