Newtons Laws Of Motion P.3

Front

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

Back

The object will not move at all.

Front

What is an example of a contact force?

Back

Friction is always a contact force.

Front

What does Newton's 3rd Law of Motion state?

Back

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

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

Why is it harder for an object to move down a hill?

Back

Friction opposes the motion, making it harder to move down.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is the relationship between force, mass, and acceleration?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is the significance of the coefficient of friction?

Back

The coefficient of friction quantifies the amount of frictional force between two surfaces.
