Forces and Motion

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

Who created the three laws of motion?

Back

Isaac Newton

Front

What is inertia?

Back

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

Front

What does the term 'velocity' refer to?

Back

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

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/h)

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, giving them weight.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (Momentum = Mass x Velocity).

Front

What is the 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.
