Newton's Laws of Motion Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in the motion of an object, causing it to accelerate, decelerate, or change direction.

Front

How do safety belts relate to Newton's First Law?

Back

Safety belts protect passengers by preventing them from continuing to move in the same direction and speed as the car during a sudden stop.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does Newton's Third Law explain the interaction between a person and a tree when pushing?

Back

When you push on a tree, the tree pushes back with an equal force in the opposite direction.

Front

What is inertia?

Back

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

Front

How does surface material affect the acceleration of a toy car?

Back

Different surface materials create varying amounts of friction, which affects how quickly the car can accelerate down the ramp.

Front

What role does gravity play in motion according to Newton's Laws?

Back

Gravity is a force that pulls objects toward the Earth, affecting their acceleration and motion.
