PS.5.2.1 Practice

Front

What is the relationship between mass and the force required to stop an object in motion?

Back

The greater the mass of an object, the more force is required to stop it when it is in motion, according to Newton's second law of motion (F=ma).

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What factors affect the distance an object rolls when a force is applied?

Back

The distance an object rolls is affected by its mass, the amount of force applied, the surface it rolls on, and friction.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the movement and can cause an object to slow down or stop.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects toward the center of the Earth, causing them to accelerate downwards at approximately 9.81 m/s².

Front

What is the effect of mass on the acceleration of an object when the same force is applied?

Back

When the same force is applied, a heavier object (greater mass) will accelerate less than a lighter object (less mass) due to the inverse relationship between mass and acceleration.

Front

What is the role of mass in determining the stopping distance of an object?

Back

The stopping distance of an object is directly related to its mass; heavier objects require more distance to stop when the same force is applied.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest and prevents it from starting to move, while kinetic friction acts on an object that is already in motion.

Front

How does surface texture affect friction?

Back

Rough surfaces generally produce more friction than smooth surfaces, affecting how easily objects can slide over one another.

Front

What is inertia and how does it relate to mass?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to mass; the greater the mass, the greater the inertia.
