Calculations/Conclusions: Multi-step Force, Mass and Acc.

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 = m * a.

Front

Define force in physics.

Back

Force is a push or pull on an object that can cause it to accelerate. It is measured in Newtons (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. It is measured in meters per second squared (m/s²).

Front

How do you calculate net force?

Back

Net force is calculated by summing all the forces acting on an object. If forces are in opposite directions, subtract the smaller force from the larger force.

Front

If a cart has a mass of 15 kg and is accelerating at 2 m/s², what is the net force acting on it?

Back

The net force can be calculated using F = m * a. F = 15 kg * 2 m/s² = 30 N.

Front

What is the formula to find acceleration?

Back

Acceleration can be found using the formula: a = F/m, where F is the net force and m is the mass.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts parallel to the surfaces in contact.

Front

How does mass affect acceleration?

Back

According to Newton's Second Law, as mass increases, acceleration decreases for a given force. This means heavier objects require more force to accelerate at the same rate as lighter objects.

Front

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

Back

The relationship is defined by Newton's Second Law: F = m * a, indicating that force is the product of mass and acceleration.
