Newton's Laws and Collisions Flashcard

Front

What is a force?

Back

A push or pull on an object.

Front

What is the formula to calculate force?

Back

F = m * a (Force = mass * acceleration)

Front

If a 20 kg bike accelerates at 10 m/s², what is the force?

Back

200 Newtons

Front

What is net force?

Back

The total force acting on an object, taking into account all individual forces.

Front

What is the direction of movement if the net force is 50 Newtons to the left?

Back

Left

Front

Which ball will have greater acceleration: a 52 kg ball or a 78 kg ball when the same force is applied?

Back

The 52 kg ball will have the greatest acceleration.

Front

What do you need to know to determine an object's velocity?

Back

Speed and direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is momentum?

Back

The product of an object's mass and its velocity (p = m * v).

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.
