Net Force and Speed

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in a net force of zero. The object remains at rest or continues to move at a constant speed.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, resulting in a net force that causes the object to accelerate in the direction of the greater force.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the formula to calculate time?

Back

Time = Distance / Speed.

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 acceleration.

Front

If a bus travels 20 km in 30 minutes, what is its average speed?

Back

40 km/h.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

If Steve runs 20 m North in 4 seconds, what is his velocity?

Back

5 m/s North.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
