Remediation Newton's Second Law Calculations

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

How do you calculate mass using Newton's Second Law?

Back

Mass can be calculated using the formula m = F/a, where F is the force applied and a is the acceleration produced.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

If a force of 5000 N accelerates a cannonball at 1000 m/s², what is the mass of the cannonball?

Back

5 kg.

Front

How do you calculate acceleration using Newton's Second Law?

Back

Acceleration can be calculated using the formula a = F/m, where F is the force applied and m is the mass of the object.

Front

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

Back

The unit of acceleration in the SI system is meters per second squared (m/s²).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity and is given by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

Which has more momentum: a car at rest or a bike moving at 15 mph?

Back

The bike moving at 15 mph has more momentum.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

If a 0.05 kg foam ball is launched with a force of 5 N, what is the acceleration produced?

Back

100 m/s².
