Newton's Laws and Collisions Flashcard

Front

What is the formula for force according to Newton's 2nd Law?

Back

F = M * A

Front

Which of Newton's Laws states that for every action, there is an equal and opposite reaction?

Back

Newton's 3rd Law

Front

What is defined as any push or pull on an object?

Back

Force

Front

What type of force must act on an object for it to change its motion?

Back

Unbalanced force

Front

If a force is exerted on two balls, one with a mass of 52 kg and the other with a mass of 78 kg, which ball will have the greater acceleration?

Back

The one with a mass of 52 kg will have the greatest acceleration.

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 relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is an example of a balanced force?

Back

Two people pushing a car with equal force in opposite directions.

Front

What happens to an object at rest when an unbalanced force acts on it?

Back

It will start to move in the direction of the unbalanced force.
