Force and Motion 5.6D

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces that are in contact. It occurs when one object rubs against another.

Front

What type of surface creates more friction?

Back

Rough surfaces create more friction compared to smooth surfaces.

Front

What force pulls objects down towards the Earth?

Back

Gravity is the force that pulls objects down towards the Earth.

Front

What happens to a cyclist when they stop pedaling while going downhill?

Back

The cyclist continues to roll down the hill due to the force of gravity acting on them.

Front

Why do heavier objects experience more friction?

Back

Heavier objects press down harder on surfaces, increasing the friction between the object and the surface.

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 momentum?

Back

Momentum is the quantity of motion an object has, which depends on its mass and velocity.

Front

What tool is used to measure length?

Back

A meter stick is commonly used to measure length.

Front

What is a timing device used for in experiments?

Back

A timing device, like a stopwatch, is used to measure the time it takes for an event to occur.

Front

How does the height of a ramp affect the speed of a toy car?

Back

Increasing the height of a ramp generally increases the speed of a toy car as it rolls down due to the effect of gravity.
