Forces and Newton's Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force.

Front

What does acceleration depend on?

Back

Acceleration depends on the net force acting on an object and its mass. Specifically, acceleration is inversely proportional to mass.

Front

What is the relationship between mass and force according to Newton's Second Law?

Back

The force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a change in the motion of an object, causing it to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

How does mass affect acceleration when a constant force is applied?

Back

When a constant force is applied, an object with a larger mass will have a smaller acceleration compared to an object with a smaller mass.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What happens to an object in motion when no external forces act on it?

Back

It will continue to move in a straight line at a constant speed.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, giving them weight and affecting their motion.
