Newtons 2nd Law Review

Front

What is the metric unit for force?

Back

The metric unit for force is Newton (N).

Front

What happens when the net force acting on an object is zero?

Back

When the net force adds up to zero, the forces are balanced and there is no acceleration.

Front

What is the term for the tendency of a moving object to continue moving at the same velocity?

Back

Inertia.

Front

How do you calculate acceleration using mass and net force?

Back

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

If a 5 kg block has an acceleration of 2 m/s², what is the net force acting on it?

Back

The net force is 10 Newtons (5 kg x 2 m/s²).

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, causing an object to accelerate.

Front

What is the effect of increasing mass on acceleration if the net force remains constant?

Back

If the net force remains constant, increasing mass will result in a decrease in acceleration.

What is the significance of the direction of net force?

Back

The direction of net force determines the direction of acceleration.
