Force and Motion

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

How does friction affect a moving object?

Back

Friction causes the moving object to slow down and eventually stop.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If a lizard can run 8 m across the water in 4 seconds, how fast is he traveling?

Back

2 m/s.

Front

Who formulated the laws of motion?

Back

Sir Isaac Newton.

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 at a constant velocity unless acted upon by a net external force.
