Forces and Motion

Front

What is the formula to calculate Force?

Back

Force = mass x acceleration

Front

What does Newton's second law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is acceleration?

Back

Acceleration is a change in speed, a change in direction, or both.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changing its motion.

Front

What is the relationship between mass and force?

Back

More mass requires more force to achieve the same acceleration.

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 unless acted upon by a net external force.

Front

What is Newton's third law of motion?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is velocity?

Back

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

Front

What is the law of universal gravitation?

Back

Every mass attracts every other mass in the universe, and the force of attraction is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
