Newtons Laws Of Motion

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 a net external force.

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

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no acceleration.

Front

What is the weight force?

Back

The weight force is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W=mg).

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

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

Back

As mass increases, acceleration decreases for a given net force.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The object will not move, as the forces cancel each other out.

Front

What is inertia?

Back

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

Front

What is the role of net force in motion?

Back

Net force determines the acceleration of an object; if the net force is zero, the object will not accelerate.
