Forces and Motion

Front

What is a reference point in motion?

Back

A reference point is a stationary object or location used to determine if another object is in motion.

Front

State Newton's Third Law of Motion.

Back

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

Front

Define acceleration in terms of motion.

Back

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

Front

What formula is used to calculate speed?

Back

Speed = Distance / Time.

Front

What does Newton's Second Law of Motion state?

Back

Newton's Second Law states that Force equals mass times acceleration (F = ma).

Front

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

Back

The unit of force is the Newton (N).

Front

How does mass affect acceleration according to Newton's Second Law?

Back

According to Newton's Second Law, as mass increases, acceleration decreases if the same force is applied.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
