Forces and Motion

Front

What does Newton's Third Law of Motion state?

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 is the definition of net force?

Back

The net force is the overall force acting on an object, taking into account all individual forces. For example, 400 N down.

Front

What formula is used to calculate speed?

Back

Speed = Distance / Time.

Front

According to Newton, which objects are affected by gravity?

Back

All objects in the universe are affected by gravity.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravity.

Front

What is inertia?

Back

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

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact.

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 the formula for calculating acceleration?

Back

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