Laws of Motion Test and Kepler's laws

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is a force?

Back

A force is defined as a push or a pull that can cause an object to accelerate.

Front

Newton's third law states....

Back

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

Front

An object is _____ if its position changes.

Back

An object is in motion if its position changes relative to a reference point.

Front

Planets orbit the Sun in a shape called a(n) __________.

Back

Planets orbit the Sun in an elliptical shape.

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 unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What does the term 'acceleration' mean?

Back

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

Front

What is Kepler's first law of planetary motion?

Back

Kepler's first law states that planets move in elliptical orbits with the Sun at one focus.
