Newtons Laws of Motion

Front

What happens when two boys pull with the same amount of force?

Back

They will not move at all.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What makes it harder for an object to move down a hill?

Back

Friction.

Front

What do the letters F, m, and a represent in physics?

Back

Force, Mass, Acceleration.

Front

What can be said about the forces acting on a stationary object?

Back

The forces are balanced.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m * a).

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force is constant.
