Energy Force Work and Motion Test

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account both the magnitude and direction of all individual forces. It determines the object's motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate or change its motion. They occur when the total force acting on an object is not zero.

Front

What is the SI unit for force?

Back

The SI unit for force is the Newton (N).

Front

What does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph indicates that the object is at rest and not moving.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed, meaning the object is moving quickly.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the SI unit for acceleration?

Back

The SI unit for acceleration is meters per second squared (m/s²).

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.
