PS.5.2.1 (5.P.1.4) #1: Schoolnet

Front

What happens to objects when a force is applied and then suddenly stopped?

Back

Objects in motion tend to stay in motion due to inertia. If a cart is stopped suddenly, the books on it will slide off the front due to their inertia.

Front

What is the relationship between mass and movement when equal force is applied?

Back

When equal force is applied, the object with less mass will accelerate more and move farther than the object with greater mass.

Front

How does adding weight to an object affect the force needed to move it?

Back

Adding weight increases the force needed to move the object because more force is required to overcome inertia and gravity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is the effect of gravity on moving objects?

Back

Gravity pulls objects toward the Earth, affecting the force needed to move them. Heavier objects require more force to move.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How can you reduce the force needed to move heavy objects?

Back

You can reduce the force needed by using smaller boxes, which are easier to lift and move.

Front

What happens when two objects of different masses are pushed with the same force?

Back

The object with less mass will accelerate more and move farther than the object with greater mass.

Front

What is the role of friction in moving objects?

Back

Friction is a force that opposes motion. It can make it harder to move objects, requiring more force.

Front

How does the amount of force applied affect the speed of an object?

Back

The greater the force applied to an object, the greater its acceleration and speed will be.
