Newton's 3 Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What does Newton's 1st Law state?

Back

Newton's 1st Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F=ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia. This means heavier objects are harder to start or stop moving than lighter objects.

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph indicates that the object is at rest and not moving.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope on a distance-time graph indicates that the object is moving quickly.
