Forces

Front

What is the formula for net force according to Newton's Second Law?

Back

F_net = ma, where F_net is the net force, m is mass, and a is acceleration.

Front

What does Newton's First Law state about an object at rest?

Back

An object at rest will tend to stay at rest unless acted upon by a net external force.

Front

In which direction does the net force act when an elevator accelerates upward?

Back

The net force acts upward.

Front

If a child pulls a toy with a force of 25 N to the right and another child pulls with 15 N to the left, what is the net force?

Back

The net force is 10 N to the right.

Front

What direction does friction act when a sled is pulled to the left?

Back

Friction acts to the right.

Front

What is the definition of net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

What is inertia according to Newton's First Law?

Back

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

Front

How does mass affect the acceleration of an object when a constant force is applied?

Back

Greater mass results in less acceleration for the same applied force, according to F=ma.

Front

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

Back

Force is directly proportional to the product of mass and acceleration.

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero.
