Newton's Law & Motion Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as the formula: F = ma.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

How do you calculate force?

Back

Force can be calculated using the formula: F = ma, where 'm' is mass and 'a' is acceleration.

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

Back

A flat line on a distance-time graph represents an object at rest.

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line on a distance-time graph represents an object moving at a constant speed.

Front

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

Back

A curved line on a distance-time graph represents an object that is accelerating.

Front

If a car is accelerating, what happens to its speed?

Back

If a car is accelerating, its speed is increasing over time.
