Understanding Forces and Motion

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will stay in motion until an outside force acts upon it.

Front

What is Newton's 2nd Law of Motion?

Back

The force exerted by an object is equal to its mass multiplied by its acceleration (F = m × a).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is a non-contact force?

Back

A force that acts on an object without physical contact, such as gravity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object in contact with a surface.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

How do you calculate force using Newton's 2nd Law?

Back

Force (F) is calculated by multiplying mass (m) by acceleration (a): F = m × a.

Front

What happens to passengers in a car when it suddenly stops?

Back

Passengers lurch forward due to inertia.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.
