READING COMPREHENSION

Front

What is the relationship between force and motion?

Back

A force causes a change in the speed of an object.

Front

When does a moving body come to rest?

Back

A moving body comes to rest when there is no force acting upon it.

Front

What did Kepler deduce about planetary motion?

Back

Kepler deduced the laws that describe the motion of planets around the sun.

Front

What are the general principles of dynamics?

Back

The general principles of dynamics are rules demonstrating the relationship between the motions of bodies and the forces producing them.

Front

What does an action force induce according to Huygens?

Back

An action force induces a change in speed.

Front

Define 'force' in the context of motion.

Back

A force is an influence that causes an object to undergo a change in speed, direction, or shape.

Front

What is inertia?

Back

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

Front

Explain Newton's 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

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
