Newton's Laws MC Practice AP Physics 1

Front

What is Newton's First 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 a net external force.

Front

Define net force.

Back

The vector sum of all the forces acting on an object.

Front

What is the formula for calculating force?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

Explain the concept of inertia.

Back

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

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is Newton's Second 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 significance of the slope in a position vs. time graph?

Back

The slope of a position vs. time graph represents the velocity of the object.

Front

What is gravitational force?

Back

The attractive force between two masses, which depends on their masses and the distance between them.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass and decreases with greater distance between the objects.

Front

What is the relationship between acceleration and net force?

Back

Acceleration is directly proportional to net force and inversely proportional to mass (a = F/m).
