Force and Motion

Front

What is speed?

Back

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

Front

What is the formula for calculating speed?

Back

The formula for speed is S = d/t, where S is speed, d is distance, and t is time.

Front

What is net force?

Back

Net force is the overall force acting on an object when all of the individual forces are combined.

Front

What is friction?

Back

Friction is a force that resists motion when two surfaces rub against each other.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

How do you calculate net force?

Back

Net force can be calculated by adding all the forces acting on an object, taking into account their directions.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).
