Force and Motion 1 (Introduction to Force and Motion)

Front

What is force in the context of motion?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does friction affect the speed of an object?

Back

More friction decreases the speed of an object, while less friction allows it to move faster.

Front

What are the two types of surfaces that can affect friction?

Back

Rough surfaces increase friction, while smooth surfaces decrease friction.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the effect of a force acting in the direction of motion?

Back

A force that acts in the direction of motion can increase the speed of the object.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their motion.

Front

What is the impact of adding sand to snow-covered highways?

Back

Adding sand increases friction, which can help vehicles gain traction on slippery surfaces.

Front

What is the significance of ramp surfaces in experiments?

Back

The surface of a ramp affects the amount of friction, which in turn influences the speed of an object rolling down the ramp.
