8.9 Newton's Second Law Test GL 2023

Front

What unit do we measure force in?

Back

Newtons

Front

What does Newton's 2nd Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the combination of all the forces acting on an object called?

Back

Net force

Front

What is the formula for calculating force?

Back

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

Front

What is acceleration?

Back

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

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²)

Front

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

Back

For a constant force, an increase in mass results in a decrease in acceleration.

Front

What is inertia?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the unit of weight?

Back

Newtons (N)
