Front

What is the responding variable in an experiment?

Back

The responding variable is the factor that is measured or observed in an experiment, often referred to as the dependent variable.

Front

In a collision, which object experiences a greater effect if their masses are very different?

Back

The less massive object will experience a greater effect from the force of the collision.

Front

What does it mean when multiple objects experience the same size force?

Back

It means that the force applied to each object is equal, regardless of their masses or velocities.

Front

How is momentum calculated?

Back

Momentum is calculated by multiplying an object's mass by its velocity (Momentum = Mass x Velocity).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

Which has greater inertia: a parked semi-truck or a scurrying cockroach?

Back

A parked semi-truck has greater inertia because it has a much larger mass compared to a scurrying cockroach.

Front

What is the relationship between mass and speed in determining momentum?

Back

Momentum depends on both mass and speed; an object with greater mass or greater speed will have more momentum.

Front

What happens to the speed of a car going down a ramp if the mass of the car increases?

Back

The speed of the car may not necessarily increase with mass; the ramp's incline and friction also play significant roles.

Front

What is the effect of force on an object with a larger mass compared to a smaller mass?

Back

An object with a larger mass will accelerate less than a smaller mass when the same force is applied, according to Newton's second law of motion.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.
