Friday Science Final

Front

What is the definition of force?

Back

A push or pull.

Front

Describe the contribution that Isaac Newton had on our understanding of motion.

Back

Newton's laws of motion describe the relationship between a body and the forces acting upon it.

Front

Define velocity.

Back

The change in distance over time with direction.

Front

Fill in the blank: The weakest of the 4 fundamental forces is the ________ force.

Back

Gravitational.

Front

Fill in the blank: A magnetic field is produced around a ______.

Back

Current-carrying wire.

Front

What are Newton's three laws of motion?

Back

1. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force. 2. Force equals mass times acceleration (F=ma). 3. For every action, there is an equal and opposite reaction.

Front

What is the difference between speed and velocity?

Back

Speed is the rate of change of distance, while velocity includes direction.

Front

What is gravitational force?

Back

The force of attraction between two masses.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is acceleration?

Back

The rate of change of velocity over time.
