Newton's Laws

Front

An object at rest will _______ if no outside forces are applied.

Back

Stay at rest

Front

For a force on an object there is an equal and opposite force. This is known as:

Back

Newton’s third law of motion

Front

When the net force is zero, the forces on an object are:

Back

Balanced

Front

An object acted upon by a net force will accelerate in the direction of the force according to the equation: Acceleration = net force/mass. This is known as:

Back

Newton's 2nd Law

Front

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?

Back

The one with a mass of .52 kg will have the greatest acceleration.

Front

What is the first 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 does the second law of motion state?

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 formula for calculating force?

Back

Force = mass x acceleration (F = ma)

Front

What is inertia?

Back

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

Front

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

Back

It continues to move at a constant velocity.
