What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What does it mean for an object to have constant velocity?

Back

An object has constant velocity when it is moving at a steady speed in a straight line without changing direction.

Front

How can you determine the net force acting on an object?

Back

The net force is determined by adding all the forces acting on an object, taking into account their directions.

Front

What is the relationship between mass and force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

What happens to an object at rest when no net force acts on it?

Back

An object at rest will remain at rest if no net force acts on it, according to Newton's first law of motion.

Front

What is the formula for calculating speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance/Time).

Front

What does it mean if an object's speed is decreasing?

Back

If an object's speed is decreasing, it is experiencing negative acceleration, also known as deceleration.

Front

What is the significance of a flat line on a distance-time graph?

Back

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

Front

How do you identify the time interval during which an object's speed is increasing?

Back

Look for sections on a speed-time graph where the line slopes upwards; this indicates increasing speed.
