Forces and Motion

Front

What is speed?

Back

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

Front

What is the formula to calculate speed?

Back

The formula to calculate speed is: Speed = Distance / Time.

Front

What is velocity?

Back

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

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

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, considering their directions.

Front

What is a reference point?

Back

A reference point is a stationary object or location used to determine the position or motion of another object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.

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).
