Forces and Newton's Laws

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 an unbalanced force.

Front

What is the definition of force?

Back

A force is a push or pull on an object resulting from the object's interaction with another object.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

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

What does Newton's 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 (F = ma).

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as Weight = mass × gravitational acceleration (W = mg).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting the motion of objects, especially those in free fall.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.
