Newtons Second Law Ch 5

Front

What does Newton's Second Law state?

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 (F = ma).

Front

If the mass of an object is doubled while the force remains constant, what happens to its acceleration?

Back

The acceleration halves.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = F/m, where F is the net force and m is the mass.

Front

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

Back

Force is the product of mass and acceleration (F = ma).

Front

How does friction affect the net force acting on an object?

Back

Friction opposes the motion of an object, reducing the net force acting on it.

Front

What is pressure and how is it calculated?

Back

Pressure is defined as force per unit area (P = F/A).

Front

In a scenario where two objects of different masses are dropped simultaneously, which object experiences a greater gravitational force?

Back

The object with greater mass experiences a greater gravitational force.

Front

What is the net force acting on an object?

Back

The net force is the total force acting on an object after all the forces are combined, taking into account their directions.

Front

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

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

Back

The unit of force is the Newton (N).
