Force and motion

Front

What does Newton's third law state?

Back

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

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 are the three laws of motion proposed by Newton?

Back

1. Law of Inertia 2. Law of Force and Acceleration 3. Law of Action-Reaction

Front

What kind of force do charged particles exhibit?

Back

Electromagnetic force.

Front

What happens to a rock thrown in space?

Back

It experiences no force acting against it.

Front

Define force in the context of physics.

Back

A force is a push or pull on an object that can cause it to accelerate.

Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.
