Forces Final Review

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it possesses.

Front

Why does an 18-wheeler have more inertia than a bicycle?

Back

An 18-wheeler has more inertia than a bicycle because it has more mass.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma). If force is constant, mass and acceleration are inversely proportional.

Front

If an object is stationary, what can we say about the forces acting on it?

Back

If an object is stationary, the forces acting upon it are balanced.

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: Acceleration = Force / Mass.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is mass?

Back

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

Front

What is acceleration?

Back

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