What is the definition of force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity is speed with a direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a change in the motion of an object, causing it to accelerate.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What does a distance-time graph represent?

Back

A distance-time graph shows how the distance of an object changes over time.

Front

What does a horizontal line on a distance-time graph indicate?

Back

A horizontal line indicates that the object is at rest and not moving.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.
