Force, Motion, & Newtons Laws Review(Part 2)

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the formula for calculating net force?

Back

Net force = Sum of all forces acting on an object.

Front

What does inertia mean?

Back

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

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 (F = ma).

Front

What is Newton's 3rd law of motion?

Back

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

Front

If two forces act in the same direction, how do you find the net force?

Back

Add the magnitudes of the two forces together.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion.

Front

How does mass affect acceleration according to Newton's 2nd law?

Back

Greater mass results in less acceleration for the same amount of force applied.
