Motion Test

Front

What is the formula for calculating time when distance and speed are known?

Back

Time = Distance / Speed

Front

What is Newton's second law of motion?

Back

F = ma (Force equals mass times acceleration)

Front

Define an inclined plane.

Back

A flat sloping surface that connects lower and higher elevations, making it easier to raise objects.

Front

What is the net force if a 10 N force is acting downward and a 6 N force is acting upward?

Back

4 N downward

Front

What type of simple machine is a screw?

Back

A device that converts rotational motion into linear motion, often used to hold objects together.

Front

How do you calculate the net force acting on an object?

Back

Net force = Sum of all forces acting on the object.

Front

What is the relationship between mass, acceleration, and force?

Back

According to Newton's second law, force is directly proportional to mass and acceleration.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

How do you calculate the distance traveled if speed and time are known?

Back

Distance = Speed x Time
